Participants

Reaction Steps

A mixture of 5-amino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.6 g) and ethyl formate (10 ml) is refluxed for 4 hours. The reaction solution is concentrated and the resulting residue is recrystallized from ethanol/petroleum ether to give 5-formylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.38 g) as colorless columnar crystal, m.p. 211°-213° C.
