실험 절차

A solution that consists of 230 mg (0.45 mmol) of 5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentylidenamino]quinoline-2-carboxylic acid diethylamide and 0.132 ml (0.58 mmol) of titanium tetraethylate in 14 ml of ethanol is mixed with 135 mg (3.55 mmol) of sodium borohydride. After 6 hours at room temperature, the reaction is halted by adding saturated socium chloride solution and ethyl acetate. The precipitate that is produced is suctioned off on Celite. The filtrate is washed with saturated sodium chloride solution, and it is dried on sodium sulfate. After removal of the solvent and purification on silica gel with hexane-ethyl acetate (0–70%), 220 mg (92%) of the product is obtained.
