2-Chloro-5,11-dihydro-11-ethyl-5-methyl-8-phenylethynyl-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (0.33 g) was prepared from 2-chloro-5,11-dihydro-11-ethyl-8-iodo-5-methyl-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one and phenylacetylene by a procedure analogous to that described in Example 42a. Hydrogenation as described in Example 42b afforded 0.18 g of the title compound as white needles, m.p. 128°-129.5° C.
