실험 절차

A solution of 2.03 g (6.36 mmol) of methyl (R)-3-(4-allylphenyl)-2-tert-butoxycarbonylaminopropionate (prepared as in Synlett, 2005, 12, 1877-1880) in 20 ml of dioxane/water (1:1, v/v) and 0.30 g (12.71 mmol) of lithium hydroxide was stirred at RT for 2 h and then neutralized with 1N hydrochloric acid. The reaction mixture was extracted with ethyl acetate, and the organic phase was dried over Na2SO4, filtered and concentrated. 1.90 g of the title compound were obtained.
