Procedure

To a solution of 5-methylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.6 g) in methanol (10 ml) is added glycolonitrile (50%, 0.19 ml) and the mixture is stirred at room temperature for 20 minutes, and then refluxed for 30 minutes. Thereto is added additional glycolonitrile (0.5 ml) and the mixture is refluxed for 5.5 hours. The reaction solution is concentrated and to the resulting residue is added ethyl acetate. The precipitated crystal is collected by filtration, and recrystallized from acetonitrile to give 5-(N-methyl-N-cyanomethylamino)-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.32 g) as colorless needles, m.p. 227°-228° C.
