Abstract

Abstract The synthesis of ketanserin (5) and its hydrochloride salt (5. HCl) using respectively equimolar amounts of 3-(2-chloroethyl)-2, 4-(1H, 3H)-quinazolinedione (2) with 4- (parafluorobenzoyl) piperidine (3) and dihydro-5H-oxazole (2, 3-b) quinazolin-5-one (1) with hydrochloride salt of 4-(parafluorobenzoyl) piperidine (3. HCl) is reinvestigated. The one-pot reaction of ethyl-2-aminobenzoate with ethyl chloroformate and ethanol amine has ...
