Procedure

The title compound was prepared from 5,11-Dihydro-11-ethyl-5-methyl-8-[trans-2-(4-pyridyl)ethen-1-yl]-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (0.38 g, 1.0 mmol) by catalytic hydrogenation over platinum oxide in ethyl acetate at 150 p.s.i. and 60° C. Recrystallization from ethyl acetate/hexanes afforded 0.18 g of the product as off-white crystals, m.p. 109°-110° C.
