Reaction Steps
3-Methoxypropan-1-ol (217 mg, 2.40 mmol), 4-fluoro-3-(trifluoromethyl)benzoic acid (500 mg, 2.40 mmol), and NaH (240 mg, 6.0 mmol) were combined in THF (10 mL) and DMF (1 mL) at 0° C. under an atmosphere of nitrogen. The reaction mixture was stirred for 16 h at room temperature. The reaction mixture was partitioned between ethyl acetate and a 1M aqueous solution of hydrochloric acid. The layers were separated and then the organic layer was washed with a saturated aqueous solution of sodium chloride, dried over sodium sulfate, and evaporated to dryness. The crude material was purified by column chromatography utilizing a gradient of 0-5% methanol in dichloromethane to yield 4-(3-methoxypropoxy)-3-(trifluoromethyl)benzoic acid (213 mg, 32%) as a white solid. ESI-MS m/z calc. 278.1, found 279.3 (M+1)+; Retention time: 1.38 minutes (3 min run).
