반응 단계

Sodium cyanoborohydride (0.62 mL, 1 M in THF) was added to a solution of 2-amino-1-(4-fluoro-phenyl)-ethanol (80 mg, 0.52 mmol), 4-(Pyrazin-2-yloxy)-benzaldehyde (103 mg, 0.52 mmol) and glacial acetic acid (0.5 mL), in methanol (3 mL) at RT and the flask was stirred overnight. The reaction mixture was concentrated in vacuo; the residue was quenched with saturated aqueous sodium bicarbonate solution and then extracted with dichloromethane (3×4 mL). The combined organic phases were dried over anhydrous sodium sulfate and concentrated again in vacuo to yield 1-(4-fluoro-phenyl)-2-[4(pyrazin-2-yloxy)-benzyl amino]-ethanol as a white solid 62 mg, 35%).
