実験手順
2-(Bromomethyl)-1-fluoro-3-methoxybenzene (3.19 g, 14.57 mmol), (R)-3-(tert-butoxycarbonylamino)piperidine (3.0 g, 12.67 mmol), and K2CO3 (2.63 g, 19.01 mmol) were taken up in DMF (25 mL) in a 50 mL flask. The reaction mixture was stirred at room temperature for 2 h. The mixture was diluted with EtOAc (100 mL), washed with water (50 mL, ×2), dried over MgSO4, filtered, and the solvent evaporated in vacuo. The residue was purified by flash chromatography (6-50% EtOAc/hexanes) to give (R)-tert-butyl 1-(2-fluoro-6-methoxybenzyl)piperidin-3-ylcarbamate. MS ESI calc'd. For C18H22FN2O3 [M+1]+ 339. found 339.
