Benzoyl chloride → HCID 20379919, compound

Participants

Reaction Steps

A solution of 5.6 g. of benzoyl chloride was added to a stirred solution of 1.96 g. of N-propynyl piperazine, 4.04 g. of triethylamine and 100 ml. of chloroform. The mixture was stirred 4 hours, filtered and the filtrate washed in sequence with 100 ml. of water, 100 ml. of 5% aqueous potassium carbonate and 100 ml. of water. The chloroform solution was then evaporated in vacuo to produce a white solid. Crystallization from cyclohexane produced the expected white crystals of N'-benzoyl-N-propynyl piperazine, m.p. 94°-5° C.
