Versuchsvorschrift

A solution of Boc-Tle-OH (176 mg, 0.76 mmol) in NMP (3 mL) was cooled to 0° C. and treated with HATU (318 mg, 0.83 mmol) followed by NMM (0.15 mL). After 10 min, 56 (360 mg, 0.76 mmol) in NMP (2 mL) was added. The reaction mixture was allowed to warm to ambient temperature overnight. The solution was diluted with EtOAc, washed successively with 1M HCl, saturated NaHCO3, dried over anhydrous Na2SO4, filtered and concentrated to afford 57 (570 mg) which was used without further purification. Mass spectrum, m/z [686.4] (M+H)+.
