실험 절차

A solution of 2-bromo-4-fluorobenzonitrile (200 mg, 1.00 mmol), O-benzyl-D-serinamide (290 mg, 1.49 mmol) and DIEA (0.466 mL, 2.68 mmol) in DMSO (3 mL) was stirred at 100 C for 18 h. Water and EtOAc were added. The organic phase was separated, washed with 1N HCl, dried over Na2SO4, concentrated in vacuo. The residue was purified by a silica gel column, eluted with 0-60% EtOAc in hexane to give (R)-3-(benzyloxy)-2-(3-bromo-4-cyanophenylamino)propanamide (66 mg).
