실험 절차

A solution of 2-(4-methylphenyl)-2-methylpropionic acid (60.0 g), sulfuric acid (0.6 ml) and methanol (300 ml) was refluxed for 19 hr. The solvent was evaporated, and water (200 ml) was added and the mixture was extracted with chloroform. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the title compound (61.52 g) as a pale-brown oil. 1H-NMR(CDCl3)δ:1.56(6H, s), 2.32(3H, s), 3.64(3H, s), 7.13(2H, d, J=8.6 Hz), 7.22(2H, d, J=8.6 Hz). MS(EI): 192(M+).
