A solution of 2-methyl-4-pyrrolidin-1-yl-quinoline-7-carbonitrile (100 mg, 0.42 mol) in dichloromethane (1 mL) was treated at 0° C. with 30% aq. hydrogen peroxide solution (0.5 mL), tetrabutylammonium hydrogen sulfate (29 mg, 84 μmol), and 20% aq. sodium hydroxide solution (0.5 mL). After removal of the ice bath, the two-phase mixture was stirred at r.t. for 2 h, then the organic layer was separated, washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 9:1) afforded the title compound (65 mg, 60%). Light brown solid, ISP-MS m/e=256.1 ([M+H]+).
