Versuchsvorschrift
The starting material can be prepared from 1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one and diethylcarbonate in a manner analogous to that described in Example 1. After recrystallization from ethanol, there is obtained 3-phenylisoindole-1-carboxylic acid ethyl ester; m.p. 144°-147° C (decomposition).
