実験手順

A solution of (S)-7-[(S)-2-(4′-cyano-biphenyl-4-yl)-1-methoxycarbonyl-ethylcarbamoyl]-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6-carboxylic acid tert-butyl ester (85 mg) in DCM (5 mL) at 0° C. was treated with acetyl chloride, and triethylamine. The mixture was allowed to slowly warm to room temperature. After 3 hours, ethyl acetate was added and the organic layer was washed with 1N HCl. The organic layer was washed saturated sodium bicarbonate solution and brine, and dried over sodium sulfate. The solvent was removed under reduced pressure to give the crude amide. The residue was purified by flash chromatography (using hexanes/ethyl acetate, from 70:30 to 55:45, as an eluent) to give the product (76 mg).
