Participants

Reaction Steps

Methanesulfonyl chloride (19 μL, 0.24 mmol) was added dropwise to a solution of triethylamine (31 μL, 0.22 mmol) and N-({4-[4-(3-pyrrolidin-1-ylpropoxy)phenyl]tetrahydro-2H-pyran-4-yl}methyl)ethanamine (70 mg, 0.20 mmol) in dichloromethane (0.5 mL) at 0° C. then was allowed to warm to ambient temperature and stirred overnight. The reaction was quenched with NaHCO3 (10 mL), extracted using dichloromethane (3×15 mL), dried using Na2SO4 and concentrated in vacuo. The compound was purified by column chromatography on Biotage® silica gel, eluting with dichloromethane:methanol:ammonia, 96.5:3.5:0.35 to 95:5:0.5 to give the title compound as a pale brown oil (60 mg, 71%). 1H NMR (400 MHz, CDCl3) δ 7.24 (d, 2H), 6.90 (d, 2H), 4.02 (t, 2H), 3.84-3.72 (m, 2H), 3.50 (dt, 2H), 3.28 (s, 2H), 2.72-2.60 (m, 7H), 2.58-2.52 (m, 4H), 2.16 (m, 2H), 2.04 (pentet, 2H), 1.96-1.90 (m, 2H), 1.84-1.76 (m, 4H), 0.90 (t, 3H); HRMS (ESI+) 425.2469 (M+H)+.
