Reaction Steps

A mixture of 40 parts of ethyl 4-chloro-2-[(ethoxycarbonyl)amino]benzoate and 10 parts of 2-aminoethanol is stirred and heated to 160°-170° C. while the formed ethanol is distilled off. After stirring for about 30 minutes, the mixture is cooled and 2-propanol is added. The solid product is filtered off and dried, yielding 23 parts (64%) of 7-chloro-3-(2-hydroxyethyl)-2,4(1H,3H)-quinazolinedione.
