Reaction Steps

A mixture of 2,6-difluorobenzyl bromide (3.7 g, 17.8 mmol) and ethanolamine (6.46 mL, 107 mmol) in ethanol (18 mL) was heated at 75° C. for 16 h. The reaction mixture was concentrated and the resulting residue was diluted with dichloromethane (50 mL). The organic layer was partitioned with water (75 mL) and the aqueous layer extracted with dichloromethane (50 mL). Combined organic layers were dried over magnesium sulfate, filtered, and concentrated to give the title compound as a yellow solid (3.25 g). (m/z): [M+H]+ calcd for C9H11F2NO, 188.08. found, 188.1. 1H NMR (d6-DMSO, 300 MHz) δ (ppm): 7.37-7.34 (m, 1H), 7.10-7.05 (m, 2H), 4.47 (t, J=5.4 Hz, 1H), 3.75 (s, 2H), 3.42 (q, J=5.5 Hz, 2H), 2.25 (t, J=5.7 Hz, 2H), 1.82 (br s, 1H).
