Reaction Steps

By replacing 5-(4-bromophenyl)-7,8-dimethoxy-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXIIaf) in example IIba by 3-benzyl-7,8-diethoxy-5-phenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXIIaj), and MeI by ethyl iodide, and proceeding in the same manner, the abovenamed product is obtained. Yield: 36%.
