2-t-Butoxycarbonylamino-2-methylpropane-1,3-diol (20.0 g, 97.4 mmol) was suspended in isopropyl ether (200 mL), and 16.3 mL (0.100 mol) of vinyl hexanoate and lipase [Immobilized lipase from Pseudomonas sp., manufactured by TOYOBO Co., Inc., 0.67 U/mg] (0.8 g) were added thereto, followed by stirring of the mixture at room temperature for 2 hours. After the reaction mixture was filtered, the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate, 10:1-2:1) to obtain the title compound (25.0 g, yield: 85%).
