Reaction Steps

A mixture of 2-bromo-1-fluoro-4-methylsulfonylbenzene (0.8 g, 3.16 mmol), oxolan-3-amine (1.38 g, 15.8 mmol) and K2CO3 (0.87 g, 6.32 mmol) in DMSO (15 mL) was stirred at 100° C. for 5 hrs. It was cooled to r.t. and water (50 mL) was added. The mixture was extracted with EtOAc (50 mL×3) and the combined organic layers were washed with brine (50 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography (PE:EA=50:13:1) to give the title compound (0.7 g, yield: 69.16%). 1H NMR (CDCl3, 400 MHz) δ 8.00 (d, J=1.2 Hz, 1H), 7.74 (d, J=8.8 Hz, 1H), 6.67 (d, J=8.8 Hz, 1H), 5.03 (d, J=6.4 Hz, 1H), 4.23-4.13 (m, 1H), 4.07-3.98 (m, 2H), 3.96-3.87 (m, 1H), 3.83-3.76 (m, 1H), 3.03 (s, 3H), 2.43-2.32 (m, 1H), 1.98-1.88 (m, 1H). LCMS (M+H)+=320.0 (M+H)+, 322.0
