Reference Production Example 99 (0741) Ethyl 5-hydroxymethylisoxazole-3-carboxylate (1.71 g, 10.0 mmol), 2,2,2-trifluoroethylmethanesulfonate (5.34 g, 30 mmol), N,N-dimethylformamide (30 ml) and 60% sodium hydride (0.48 g, 12.0 mmol) were mixed at 0C, under a nitrogen atmosphere. The mixture was heated to room temperature and stirred for 16 hours, then added to a saturated aqueous ammonium chloride solution, and the mixture was extracted twice with ethyl acetate. The organic layer was washed with water and saturated saline water, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was applied to a silica gel column chromatography to obtain 1.02 g of ethyl 5-(2,2,2-trifluoroethoxymethyl)isoxazole-3-carboxylate represented by the following formula. 1H-NMR (CDCl3, TMS, delta (ppm)) : 1.41 (3H, t), 3.91(2H, q), 4.43(2H, q), 4.80(2H, s), 6.73(1H, s), 123770-62-7
123770-62-7 Ethyl 5-(hydroxymethyl)isoxazole-3-carboxylate 8027233, aIsoxazoles compound, is more and more widely used in various.
