Reaction Steps

To a solution of N-{(4-bromophenyl)[4-(methylsulfonyl)phenyl]methyl}-L-leucine from step 3 (76 mg, 0.17 mmol), HATU (146 mg, 0.38 mmol), aminoacetonitrile hydrochloride (52 mg, 0.56 mmol) in DMF (1.1 mL) cooled to −10° C., was added N,N-diisopropylethylamine (0.13 mL, 0.75 mmol). The reaction was allowed to proceed at room temperature for 18 h and it was partitioned between EtOAc and water. The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by chromatography using EtOAc and hexane as eluant to give the title compound as a colorless gum.
