실험 절차
To a solution of ethyl N-(tert-butoxycarbonyl)-3-(2-propenylamino)propionate (1.0 g, 3.89 mmol) in methanol (10 mL) was added 1N aqueous LiOH solution (5.0 mL). After stirring overnight, the mixture was acidified to pH 2.5 with 20% aqueous KHSO4 solution, and extracted with ethyl acetate. The extract was dried over Na2SO4, and evaporated in vacuo to give N-(tert-butoxycarbonyl)-3-(2-propenylamino)propionic acid (0.8 g, 3.49 mmol, 89.7%) as a colourless oil.
