To a solution of YD-014 (320 mg, 1.58 mmol) in anhydrous dichloromethane (10 mL) was added in sequence diisopropylethylamine (DIEA, 305 mg, 2.36 mmol), YD-05 (380 mg, 1.58 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDCI, 1.2 g, 6.30 mmol). The resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted with dichloromethane, and washed in sequence with aqueous sodium hydroxide (2 M), water and saturated brine. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The residue was purified by column chromatography eluting with petroleum ether in ethyl acetate (3:1) to give YD-01 (290 mg, 43% yield) as a light yellow solid.1H-NMR (400 MHz, DMSO-d6) delta 8.23 (d, 111, J=2.6 Hz, 1′-H), 8.15 (dd, 1H, J=9, 2.6 Hz, 2′-H), 7.63-7.60 (m, 2H, 1-H, 5-H), 7.55-7.52 (m, 3H, 2-H, 3-H, 4-H), 7.20 (d, 1H, J=9 Hz, 3′-H), 3.81 (br s, 2H, CH2), 3.39 (br s, 21-1, CH2), 3.20 (br s, 2H, CH2), 2.85 (br s, 2H, CH2), 2.50 (s, 3H, -CH3);13C-NMR (100 MHz, DMSO-d6) delta 168.8, 161.2, 159.6, 153.9, 141.9, 130.2, 129.1, 127.9, 127.3, 126.3, 125.9, 123.7, 120.6, 110.7, 50.1, 49.7, 46.3, 41.3, 11.4; LRMS (API-ES): 427 (M++H)., 1136-45-4
1136-45-4 5-Methyl-3-phenylisoxazole-4-carboxylic acid 14343, aIsoxazoles compound, is more and more widely used in various fields.
