Procedure

The crude product from Example AK ((S)-2-Amino-3-(4-nitrophenyl)-N-tert-butylpropionamide) (1.34 g, 5.25 mmol) and the product from Example Z (1.35 g, 5.25 mmol) were dissolved in DMF (40 mL), then HBTU (1.99 g, 5.25 mmol) and diisopropylethylamine (4.3 g, 33 mol) were added and stirred for 1 hour. The mixture was poured into CH2Cl2 (100 mL); the CH2Cl2 solution was washed with aqueous sodium bicarbonate (3×) and dried over sodium bicarbonate. The crude reaction mixture was further purified by column chromatography (SiO2, EtOAc) to yield the title compound (2.5 g), mp 194-195° C.
