実験手順

(2S)-2-{[(R)-(4-bromophenyl)(phenyl)methyl]oxy}-4-methylpentanoic acid from Step 2, Example 1, (46.5 g, 123 mmol) was dissolved in DMF (200 mL). To this mixture was added HATU (56.7 g, 149 mmol, 1.2 eg), Et3N (57.7 g, 570 mmol, 4.6 eg), then added at 0° C. aminoacetonitrile hydrochloride (13.5 g, 146 mmol, 1.19 eg). The resulting reaction mixture was stirred at room temperature for 3 hours; then poured into 1 L of half saturated sodium bicarbonate. The aqueous phase was extracted with EtOAc (2×500 mL). Organic fraction was washed with brine (200 mL), INHCl (200 mL), brine (200 mL), 0.5 N NaOH (300 mL), brine (200 mL). Solvent was evaporated under reduced pressure and the resulting dark red oil which was chromatographed with 20% EA/hexane to give the title compound.
