실험 절차

A mixture of 5-(4-chlorophenyl)-2-(trifluoromethyl)furan-3-carboxylic acid (0.30 g) in tetrahydrofuran (10 ml) stirred under a nitrogen atmosphere at 0° C. was treated with a 1M solution of borane in tetrahydrofuran (10.33 ml) and the reaction stirred at room temperature for 2 hours. The reaction was cooled to 0° C.; treated with methanol (4 ml) and after 15 minutes the reaction mixture was evaporated. The residue was purified by SPE (Si cartridge) sequentially using dichloromethane, chloroform and chloroform:ether (9:1) as eluents to give the title compound as a white solid.
