Reaction Steps

A 100 mL round-bottom flask was charged with 2-fluoro-4-(trifluoromethyl)benzaldehyde (1.90 g, 9.89 mmol, 1.00 equiv), morpholine (1.30 g, 14.9 mmol, 1.51 equiv), potassium carbonate (3.45 g, 25.0 mmol, 2.52 equiv), and dimethyl sulfoxide (20 mL). The resulting solution was stirred overnight at 100° C. in an oil bath and diluted with H2O (30 mL). The resulting solution was extracted with dichloromethane (2×20 mL) and the organic layers were combined, washed with H2O (3×20 mL), dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was chromatographed on a silica gel column with ethyl acetate/petroleum ether (1/5) to yield 1.06 g (41% yield) of 2-(morpholin-4-yl)-4-(trifluoromethyl)benzaldehyde as yellow oil. LCMS (ESI, m/z): 260 [M+H]+.
