실험 절차

A mixture of α-isopropyl-4-hydroxyphenylacetic acid (18.2 g, 0.094 mol) in acetic acid (130 ml) is heated to 40° C. and nitric acid (70%, 9.56 g, 0.095 mol) is added at such a rate that the reaction temperature is maintained at 38°-40° and never exceeded 45° C. The reaction mixture is stirred at 40°-42° C. overnight and poured into ice-water. The yellow solid is collected by filtration, washed and dried (19.1 g); m.p. 103°-105°.
