Reaction Steps

Chloroacetyl chloride (0.021 mL, 0.26 mmol) was added to a solution of (R)-5-(piperidin-3-ylamino)-[3,4′-bipyridin]-6(1H)-one hydrochloride (100 mg, 0.26 mmol) and triethylamine (0.17 mL, 1.2 mmol) in dichloromethane (5.0 mL) at 0° C. The solution was stirred at 0° C. for 30 min and was concentrated. The residue was diluted with water and extracted with 5% methanol in ethyl acetate. The organic layer was dried over sodium sulphate, filtered, and concentrated. The residue was purified on silica gel eluting with 10% methanol in dichloromethane to provide 20 mg of the title compound: 1H NMR (300 MHz, DMSO-d6) 11.80-11.95 (m, 1H), 8.45-8.60 (m, 2H), 7.60-7.70 (m, 2H), 7.20-7.35 (m, 1H), 6.70-6.95 (m, 1H), 5.50-5.80 (m, 1H), 4.20-4.50 m, 1H), 3.45-3.95 (m, 1H), 2.95-3.40 (m, 2H), 2.65-2.90 (m, 1H), 1.35-2.15 (m, 2H); MS (ES) m/z 347 (M+H).
