Participants

Reaction Steps

By replacing in the example 7,8-dimethoxy-5-phenyl-1,3-dihydro-1,4-benzodiazepin-2-one (XXIIaa) by 8-ethoxy-7-methoxy-5-phenyl-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXIIam), and ethylene carbonate by iodomethane, and proceeding in the same manner, the abovenamed product is obtained. Yield: 69%. M: 138–140° C. 1H-NMR (CDCl3, 200 MHz): d 1.54 (t, 3H, CH3), 3.38 (s, 3H, NCH3), 3.74 (s, 3H, OCH3), 4.18 (q, 2H, —OCH2), 4.29 (AB system, ? d=0.98, JAB=10.5, 2H, —CH2), 6.70 (s, 1H Ar), 6.77 (s, 1H Ar), 7.39–7.43 (m, 3H Ar), 7.63–7.68 (m, 3H Ar).
