CARBOXYLIC ACID 8; 3-Trifluoromethyl-4- (2- (S)-butoxy) benzoic acid; Step A:; 3-Trifluoromethyl-4- (2- (S)-butoxy) benzonitrile; A solution of 1.1 g (5.9 mmol) of <strong>[67515-59-7]4-fluoro-3-trifluoromethylbenzonitrile</strong> and 485 mg (6.5 mmol) of (S)- (+)-2-butanol in 10 mL of THF at-10C was treated with 235 mg (5.9 mmol) of sodium hydride. The resulting mixture was stirred cold for 2 h, then quenched with 10 mL of H20. The quenched solution was extracted with 30 mL of Et20, dried over MgS04 and concentrated.
