To a solution of 4-chloro-3-{5-[(2-cyclohexylethylamino)methyl]pyridin-2-yl}benzonitrile (170 mg, 0.48 mmol) in DMSO (4 mL) was added K2CO3 (66 mg, 0.48 mmol) and 70% hydrogen peroxide (0.5 mL, 4.8 mmol). The mixture was stirred at rt for 5 h before water (5 mL) was added and the mixture partitioned between EtOAc (20 mL) and water (20 mL). The organic phase was washed with water (3×20 mL), brine (20 mL) and dried (MgSO4). The solvent was removed in vacuo and the residue purified by column chromatography (0.4% NH3: 4% MeOH: DCM) to give the title compound: RT=2.57 min; m/z (ES+)=372.2 [M+H]+.
