Procedure
1-(Biphenyl-4-yl)cyclopropanecarboxylic acid (10 g, 42 mmol), ethanol (100 mL) and sulfuric acid (40 mL) were heated to 65° C. for 4 hours. The product was extracted with CH2Cl2 and water (2×), dried and evaporated to yield 9.5 g of 1-(biphenyl-4-yl)cyclopropanecarboxylic acid ethyl ester.
