実験手順

To a solution containing Boc-Thr(tBu)-OH (138 mg, 0.5 mmol) in anhydrous NMP (4 mL) was cooled to 0° C. HATU (190 mg, 0.5 mmol) and DIPEA (111 mg, 0.8 mmol) were added followed by the addition of crude 42 (195 mg, 0.5 mmol) in anhydrous NMP (5 mL). The reaction mixture was slowly warmed to ambient temperature. After 4 h, the reaction mixture was diluted with EtOAc and washed successively with 1M HCl, aqueous NaHCO3, and brine, dried over anhydrous Na2SO4, filtered, and concentrated to afford 336 mg of crude 43 as an amber-colored foam which was used without further purification. Mass spectrum, m/z [637.3] (M+H)+.
