Procedure

To a resealable vial were added NaH (193 mg, 60% dispersion in mineral oil, 4.82 mmol) and THF. The vial was cooled to 0° C. before addition of (4-methoxyphenyl)methanol (639 μl, 5.14 mmol) and the reaction stirred at 0° C. for 30 min before addition of 3-(chloromethyl)-5-methylisoxazole (423 mg, 3.22 mmol) and tetrabutylammonium iodide (119 mg, 0.322 mmol). The reaction was heated to reflux overnight. The vial was cooled to room temperature before being diluted with ammonium chloride solution. The aqueous was extracted with EtOAc and the combined organics were washed with brine, dried over Na2SO4, filtered, and concentrated. The crude residue was purified via Biotage (EtOAc/hex) to afford 3-(((4-methoxybenzyloxy)methyl)-5-methylisoxazole. LC/MS m/z 256 [M+Na]+.
