Reaction Steps

By replacing 5-(4-bromophenyl)-7,8-dimethoxy-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXIIaf) in example IIba by 7,8-dimethoxy-5-phenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXIIaa), and MeI by benzyl bromide, and proceeding in the same manner, the abovenamed product is obtained. Yield: 64%. M: 148–149° C. 1H-NMR (CDCl3, 200 MHz): d 3.67 (s, 3H, OCH3), 3.83 (s, 3H, OCH3), 4.38 (AB system, ? d=0.96, JAB=10.0 2H, CH2), 5.15 (AB system, ? d=0.70, JAB=15.4, 2H, —NCH2), 6.56 (s, 1H Ar), 6.81 (s, 1H Ar), 7.07–7.46 (m, 10H Ar).
