Ok will send you methods

@scientist9279 how and when?

@@REDOXorg send me way I will send you and tomorrow

@@scientist9279 do you have any contact?

Open Settings from the Start menu and click on the "Time & Language" It will open another Window in that click on "Region" and then click on the "Additional date, time, & regional settings hyperlink In the new window click on "Change date, time or number formats" present under "Region" Then click on the "Additional settings" button in the Region dialog box Check for "Decimal symbol", if that is , (comma) change it to .(dot) and click the OK button and retest the problem.

Synthesis of imidazole based derivatives

It is the synthesis of it's derivatives using Triethylamine, benzyl chloride and using respective piperazine derivatives

@@girjabaghel7899 I got installed from my institute

Chemdraw professional pls send activation cod

Request request sir ji

Yes

Hello dear I have sci finder access but I am out of city I will be back at 20th of September then you may send whatever you want to

Yes

I have not synthesized it in lab because we bought from the sigma Aldrich

Thank you

1,2-dibromoethane was reacted with 1,2-diaminoethane and Triethylamine as base and further more reacted with various alkyl halides, benzoyl chloride and much more

Its written as "NaOH" hydrogen is also an element here

Reaction of phenyl piperidine with different phenyl isothiocyanate in presencr Acetonitrile and Triethylamine as base

Nitrosation of N-Phenylpiperidine To a solution of'30.0 gm. (0.200 mole) of X-phenylpiperidine in 12 N hydrochloric acid (0.440 mole) was added 13.9 gm. (0.202 mole) of sodium nitrite dissolved in 18 ml. of water. The addition, conducted with constant stirring in a nitrogen atmosphere at 3-5OC., required 45 min. After stirring for an additional 30 min. the solid N-(p-nitrosopheny1)-piperidine hydrochloride was separated by filtration; yield, 30-33 gm. or 70-75%. Purification was effected by conversion of the hydrochloride to the free base with alkali, crystallization of the base from isopropanol, reprecipitation of the salt by passing anhydrous hydrogen chloride into an ether solution of the base, and a final crystallization of the salt from methanol. The pure hydrochloride consisted of lemon-yellow crystals which exhibited no definite melting point.

Hydrolysis oj N-(p-Nitrosopheny1)-piperidine The entire nitrosation reaction mixture obtained from the nitrosation of 30.0 gin. (0.200 mole) of N-phenylpiperidine mas transferred to a 2-liter flask and 33.6 gm. (0.840 mole) of sodium hydroxide dissolved in 1300 ml. of water added. The flask was attached to a 20-plate Fenske column and heated under total reflux for 30 min. A distillate boiling at 92-95OC., the piperidine-water azeotrope, was then collected slowly. The over-all yield of piperidine, obtained as a 60-65yo by weight aqueous solution, was 65-70y0 based on N-phenylpiperidine. When the crude solid hydrochloride was used in the hydrolysis reaction, the yield based on the salt was 75-80yo and the over-all yield 52-57yo

Thank you for appreciation and hot plate name is heidolph Mr hei- standard, there are various company which provides such as fisher scientific

@@scientist9279 Thank you Sir. May I know that heating blocks cost and where can I get it? Is the is made up of iron or stone or aluminium. I can see RB flask was kept on it.

@@sarvanks7711 dear I do not have idea about the prices because I have received from my institute

@@sarvanks7711 it is made of iron but there are aluminum based

@@scientist9279 Okay sir. Thanks for your kind reply. I will check online. At the meantime If you come to know about the 'Block( and its supplier. Please let me know. May I know about your lab? where is that? I am seeking one help for synthesis.

It is 16.0 something and I have got from my institute

@@scientist9279 I see, thanks for reply 🌻
