実験手順
To a stirred solution of 5-(tert-butoxycarbonylaminomethyl)-isoxazole-3-carboxylic acid ethyl ester (1.954 g) (EP 0451790) in ethanol (15 ml) was added a solution of 4.0M hydrogen chloride in 1,4-dioxane (23 ml). The mixture was stirred at 20° C. for 22 h and the solvent evaporated in vacuo to give the title compound (1.128 g) as a pale brown solid.
