Procedure

To a solution of 10,11-dihydro-10-[[2-methyl-2′-trifluoromethyl-[1,1′-biphenyl]-4-yl]carbonyl]-3-(1-piperazinylcarbonyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine hydrochloride salt of Step B (0.50 g, 0.84 mmol) and N,N-diisopropylethyl amine (0.16 mL, 0.92 mmol) in methanol (5 mL) was added (R )-(+)-glycidol (0.10 mL, 1.50 mmol). The reaction mixture was heated to 60° C. for 4 hours then cooled and concentrated in vacuo. The residue was partitioned between dichloromethane and water. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give a white foam. Purification by flash chromatography on silica gel using a solvent system of 5% methanol in chloroform provided the title product, which was redissolved in dichloromethane and evaporated to dryness in vacuo to a white foam (0.38 g).
