Reaction Steps

4-((1R,2R)-2-(((3-fluoro-4-(methylsulfonyl)benzyl)oxy)methyl)cyclopropyl)piperidine hydrochloride (Step D product, 200 mg, 0.53 mmol) was dissolved in DMSO (5 ml) at RT under N2 and Cs2CO3 (517 mg, 1.588 mmol) was added. The mixture was stirred at RT for 5 min and 2-chloro-5-ethoxypyrimidine (101 mg, 0.635 mmol) in DMSO (0.5 mL) was added. The mixture was stirred at 100° C. overnight. The mixture was diluted with EtOAc, washed with sat. NH4Cl, dried over MgSO4, evaporated. The crude material was purified by flash column (25 g SNAP, 15˜50% EtOAc in hexane) to afford 56 mg (23%) of the title compound. 1H NMR (500 MHz, CDCl3) δ 8.10 (s, 2H), 7.90 (m, 1H), 7.30 (m, 2H), 4.60 (m, 4H), 4.00 (t, 2H), 3.60 (m, 2H), 3.20 (s, 3H), 2.93-2.80 (m, 2H), 1.96 (d, 1H), 1.85 (d, 1H), 1.43 (m, 5H), 1.25 (m, 1H), 1.15 (m, 1H), 0.80-0.71 (m, 2H), 0.12-0.08 (m, 1H). MS (ESI) m/z 464 [M+H]+. GPR119 Human EC50: 1.65 nM.
