Procedure

Methanesulfonyl chloride (4 μL, 0.05 mmol) was added to a solution of (S)-1-(2-methyl-6-(piperidin-4-yl)-5-propoxy-3,4-dihydroquinolin-1(2H)-yl)ethanone (17.0 mg, 0.05 mmol) and triethylamine (0.02 mL, 0.14 mmol) in dichloromethane (1.0 mL), and the reaction stirred at room temperature overnight. The reaction solution was purified directly via column chromatography on silica gel (Biotage 10 g column, gradient elution with 10-0% hexanes in ethyl acetate) to afford (S)-1-(2-methyl-6-(1-(methylsulfonyl)piperidin-4-yl)-5-propoxy-3,4-dihydroquinolin-1(2H)-yl)ethan-1-one (14 mg, 72%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.98-1.04 (m, 6H), 1.19-1.26 (m, 1H), 1.58-1.81 (m, 6H), 2.02 (s, 3H), 2.17-2.30 (m, 2H), 2.68-2.85 (m, 3H), 2.89 (s, 3H), 2.89-2.99 (m, 1H), 3.60-3.76 (m, 4H), 4.57 (br d, J=6.45 Hz, 1H), 7.09 (br s, 2H). MS (ESI, pos. ion) m/z 409 [M+H]+.
