実験手順
2.0 g. 4-(1,1-Dimethylethyl)-N-[4-(ethoxycarbonylmethoxy)-phenyl]-benzamide (Example 31) are heated in 20 ml. 2N aqueous sodium hydroxide solution, then acidified with concentrated hydrochloric acid, filtered off with suction and washed with water. After recrystallisation from ethyl acetate, there is obtained 1.2 g. (65% of theory) of the title compound; m.p. 179°-181° C.
