Participants

Reaction Steps

0.8 Gram of 6-(4-oxo-1-piperidyl)carbonyl-3,4-dihydrocarbostyril, 1.6 ml of benzylamine and 1 g of Molecular Sieve 3A (a trademark for synthetic feldspar manufactured by Linde Co., U.S.A.) were dispersed in 15 ml of chloroform and refluxed by heating for 6 hours. Molecular Sieve 3A was removed by filtration, the filtrate was concentrated, then the residue obtained was washed several times with diethyl ether, next, purified by means of a silica gel column chromatography to obtain 6-(4-benzylimino-1-piperidyl)carbonyl-3,4-dihydrocarbostyril.
