反応手順
Dissolve 4-(cyclopropylcarbonyl)benzeneacetic acid in ethanol (150 mL) containing concentrated sulfuric acid (10 drops). Stir 24 hours. Add triethylamine (2 mL) and concentrate the solution. Dissolve the residue in water/ethyl acetate. Wash the organic phase with saturated sodium hydrogen carbonate solution, dry over anhydrous magnesium sulfate and concentrate. Purify by silica gel chromatography (400 mL silica gel, 20% ethyl acetate/heptane as eluent) to give the title compound (7.0 g, 88%).
