A mixture of amine salt 11 (0.31 g, 0.45 mmol) and N-Ac-Tle-OH (0.10 g, 0.58 mmol) in anhydrous DMF (8 mL) was treated with DIEA (0.60 mL, 3.50 mmol) and HATU (0.35 g, 0.92 mmol). The resulting reaction mixture was stirred at room temperature for 5 h, then diluted with EtOAc (100 mL), and washed successively with aqueous 0.5 Ν HCl, saturated aqueous NaHCC , and saturated aqueous NaCl (75 mL each). The organic portion was dried (Na2S04), filtered, and evaporated under reduced pressure. The residue was purified by flash column chromatography (RediSep Gold column, 12 g, gradient elution with 80-100% EtOAc/hexanes) to provide P4-P5-2 (0.28 g, 77%) as a white solid.
