With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2510-36-3,3,5-Dimethylisoxasole-4-carboxylic acid,as a common compound, the synthetic route is as follows.

A solution of 2-{3-[(3-bromo-5-chlorophenyl)oxy]-4-chloro-2- fluorophenyl}acetohydrazide (400 mg, 0.98 mmol), 3,5-dimethyl-4- isoxazolecarboxylic acid (138 mg, 0.98 mmol), HATU (373 mg, 0.98 mmol) and DIPEA (0.34 mL, 1.96 mmol) in THF (5 mL) was heated at 45 C overnight. The reaction was cooled to rt, Burgess Reagent (933 mg, 3.92 mmol) was added and the reaction was stirred overnight. The reaction mixture was diluted with water (20 mL) and extracted with ethyl acetate (3 x 20 mL). The organic extracts were combined, dried over Na2SO4, filtered, concentrated and the crude material was purified by column chromatography (5% to 100% EtOAc/hexanes gradient) to afford the title compound (350 mg, 70%) as a white solid. 1H NMR (400 MHz, DMSO-c/6): delta ppm 7.55-7.48 (m, 3H), 7.15 (t, 1 H), 7.08 (t, 1 H), 4.46 (s, 2H), 2.62 (s, 3H), 2.38 (s, 3H).

2510-36-3, 2510-36-3 3,5-Dimethylisoxasole-4-carboxylic acid 75636, aIsoxazoles compound, is more and more widely used in various.

Example 219 3,5-Dimethyl-isoxazole-4-carboxylic acid [4-chloro-5-(l-methyl-2-oxo-l,2,3,4- tetrahydro-quinolin-6-yl)-pyridin-3-ylmethyl]-amideTo a solution of 6-(5-aminomethyl-4-chloro-pyridin-3-yl)-l-methyl-3,4-dihydro-lH- quinolin-2-one hydrochloride (example 218, 0.05 g, 0.148 mmol) in dry DMF (1 mL) were added EDCI (0.034 g, 0.077 mmol), hydroxybenzotriazole (0.017 g, 0.077 mmol), Hunig’s base (0.057 g, 0.443 mmol) and 3,5-dimethyl-isoxazole-4-carboxylic acid (0.021 g, 0.148 mmol) and the resulting solution was stirred at room temperature for 2h. The reaction mixture was diluted with EtOAc, poured into sat. NaHC03 solution (10 mL) and extracted with EtOAc (2 x 20 mL). Combined organics were dried over Na2S04, filtered and evaporated to dryness. The residue was purified by silica gel flash chromatography eluting with a 0 to 5% MeOH-DCM gradient to give the title compound (0.03 g, 48 %) as a colorless solid. MS: 425.4 (M+H+)., 2510-36-3
