Reaction Steps

To a mixture of tert-butyl piperidin-4-ylmethylcarbamate 93-1 (1.07 g, 5.0 mmol), 2-fluoroisonicotinic acid 93-2 (706 mg, 5.0 mmol) and HATU (1.90 g, 5.0 mmol) in DMF (20 mL) was added DIEA (2.5 mL, 15.0 mmol) at room temperature. The mixture was stirred for 2 hours. The mixture was diluted with ethyl acetate (100 mL), washed with H2O and brine, dried over Na2SO4, and concentrated to dryness by rotary evaporation. The crude product was purified by silica gel flash chromatography, and eluted with 5% methanol in dichloromethane to give tert-butyl (1-(2-fluoroisonicotinoyl)piperidin-4-yl)methylcarbamate 93-3 as a pale yellow solid.
