Using a procedure analogous to that described in Example 98, except sodium bis(trimethylsilyl)amide was employed as the base instead of potassium tert-butoxide, the title compound, m.p. 140°-141° C., was prepared from 2-chloro-8-chloromethyl-5,11-dihydro-11-ethyl-5-methyl-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one and phenol. The yield was 78% of theory.
