Procedure
From 20 g (0.061 mol) of 7-amino-5-(o-chlorophenyl)-1,3-dihydro-1,3,3-trimethyl-2H-1,4-benzodiazepin-2-one there is obtained, in analogy to the details in Example 45, 7-amino-6,8-dichloro-5-(o-chlorophenyl)-1,3-dihydro-1,3,3-trimethyl-2H-1,4-benzodiazepin-2-one of melting point 105° (methylene chloride/cyclohexane).
