Procedure

To a solution of N-(cyanomethyl)-4-methyl-2-{phenyl[4-(piperazin-1-ylcarbonyl)phenyl]methoxy}pentanamide from example 17, step 7 (102 mg, 0.23 mmol) in DMF (1 mL), was added methyl sulfonyl chloride (27 μL, 0.35 mmol) and cesium carbonate (91 mg, 0.28 mmol). The mixture was aged for 2 hours under nitrogen atmosphere and was diluted with dichloromethane. The resulting mixture was filtered over celite and concentrated under reduced pressure. The crude residue was chromatographed on silica gel using 1% NH4OH and 9% methanol in dichloromethane to afford the title compound.
