Procedure

Sodium hydride (60% suspension, 0.10 g, 2.5 mmol) washed with hexane and dried under nitrogen, was suspended in dry N,N-dimethylformamide (15 mL). Following addition of 1,1′-biphenyl-4-yl-(5,11-dihydro-benzo[b]pyrido[2,3-e][1,4]diazepin-6-yl)-methanone of Example 4 (0.76 g, 2.0 mmol), methyl iodide (0.15 mL, 2.4 mmol) was added. After stirring for 1 hour, the reaction was quenched with water and extracted with dichloromethane The organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo to give a yellow solid. Purification of the residue by flash chromatography using a solvent gradient from 25% to 35% of ethyl acetate in hexane gave a white foam which was redissolved in dichloromethane, concentrated in vacuo to a foam, then crystallized by sonication from ethyl acetate/hexane to provide the title compound (0.48 g, 61.3%) as a white solid, m.p. 220-223° C.
