8-Bromo-2-fluoro-5,11-dihydro-11-ethyl-5-methyl-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (35 mg, 0.10 mmol) was coupled with 2-vinylnaphthalene in the presence of bis(triphenylphosphine)palladium(II) chloride and (i-Pr)2NEt as described in example 1h. The product was hydrogenated as described in example 3b. Purification by flash chromatography (elution with ethyl acetate-hexanes) and recrystallization (diethyl ether-hexanes) afforded 20 mg of the title compound as white crystals, m.p. 112°-114° C.
