実験手順
To a solution of (4-bromophenyl)(thien-3-yl)methyl 2,2,2-trichloroethanimidoate from step 2 (970 mg, 2.36 mmol) in dichloromethane (12 mL) was added (2S)-N-(cyanomethyl)-2-hydroxy-4-methylpentanamide (402 mg, 2.36 mmol) and camphorsulfonic acid (137 mg, 0.59 mmol). The reaction was stirred overnight at room temperature and the resulting mixture was poured into water. The aqueous layer was extracted 3 times with ethyl acetate. The combined organic layers were washed with brine, dried and evaporated and the crude residue was chromatographed on silica gel using 50% ethyl acetate in hexanes to afford the title compound.
