実験手順

(3-tert-Butoxycarbonylamino-2-hydroxy-4-phenyl-butyl)-isobutyl-carbamic acid benzyl ester (3) (34.30 g, 72.90 mmol, 1 equiv) was dissolved in methanol (170 mL), followed by the addition of 5-6 N HCl in isopropanol (75 mL). The solution was stirred at room temperature for 64 h. Volatiles were evaporated under reduced pressure. The crude product was coevaporated with ethyl acetate (150 mL) to obtain 4 as a white solid (29.70 g, 72.90 mmol, quantitative). LRMS (ES+): m/z 371 [M+H]+.
