Полученные кислоты люгут быть дебензоилированы обычными методами с количественным выходом.The resulting acids can be debenzoylated by conventional methods in quantitative yield.

Пример. 5 г 3,3-диметил-4-бензоиламиноизоксазолидопа-5 суспендируют с 100 мл воды, добавл ют 0,1 г окиси нлатины и Г1 дри эу1ог в утке. Через 30-40 мин. ноглощаетс  теоретическое количество водорода . Катализатор отфильтровывают, а фильтрат упаривают до 15- и к нему добавл ют 30 мл сиирта. Выпадает 3,8 г (около 75% от теоретического) (3,р-диметил-|3-амиио-а-бензоиламинопронионовой кислоты е т. нл. 227-229° (из водного сиирта). Из маточного раствора можно выделить еще 0,8-0,9 г вещества. Общий выход составл ет 89-93%.Example. 5 g of 3,3-dimethyl-4-benzoylaminoisoxazolidopa-5 are suspended with 100 ml of water, 0.1 g of nlatinum oxide and G1 of dry euthore are added in a duck. In 30-40 minutes The theoretical amount of hydrogen is consumed. The catalyst is filtered off, and the filtrate is evaporated to 15 and 30 ml of syirt are added to it. 3.8 g (about 75% of theoretical) drops out (3, p-dimethyl- 3-amio-a-benzoylaminopronionic acid, e. Nl. 227-229 ° (from aqueous syirt). From the mother solution, you can select another , 8-0.9 g of substance. The overall yield is 89-93%.
