Embodiment 1
[0113] Embodiment 1: the preparation of compound 1
[0114]
[0115] Add 0.50 g (0.90 mmol) 4-(5-(3,5-dichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl) to the one-necked bottle -2-methyl-N-(2-oxo-2-(2,2,2-trifluoroethyl)amino)ethylbenzamide, 25 ml toluene and 0.18 g (1.80 mmol) triethylamine, Then add 0.14 g (1.35 mmol) cyclopropylformyl chloride, and heat up to reflux for 3 hours. Water was added to the reaction solution and extracted with ethyl acetate. The organic phase was dried over anhydrous magnesium sulfate, filtered, concentrated, and purified by column chromatography to obtain 0.30 g of a white solid.
[0116] The NMR and mass spectrometry data of compound 1 are as follows:
[0117] 1 H NMR (600 MHz, DMSO- d 6 ) δ 8.82 (t, 1H), 7.81 (t, 1H), 7.69 – 7.60 (m,4H), 7.54 (d, 1H), 4.47 (s, 2H), 4.39 (d, 1H), 4.30 (d, 1H), 3.99 – 3.88 (m,2H), 2.38 (s, 3H), 1.77 – 1.68 (m, 1H), 0.84 –0.64 (m, 4H). ESI-MS, m / Z :646.24 [M+H+Na] + .
Embodiment 2
[0118] Embodiment 2: the preparation of compound 2
[0119]
[0120] Compound 2 (yellow solid) was prepared according to the synthesis method of Example 1. The NMR and mass spectrometry data of compound 2 are as follows:
[0121] 1 H NMR (600 MHz, DMSO- d 6 ) δ 8.86 (t, 1H), 7.85 (d, 2H), 7.71 – 7.63 (m,2H), 7.58 (d, 1H), 4.51 (s, 2H), 4.42 (d, 1H), 4.35 (d, 1H), 4.04 – 3.93 (m,2H), 2.42 (s, 3H), 1.83 – 1.74 (m, 1H), 0.88 –0.70 (m, 4H). ESI-MS, m / Z :664.15 [M+H+Na] + .
Embodiment 3
[0122] Embodiment 3: the preparation of compound 19
[0123]
[0124] Add 0.50 g (0.90 mmol) 4-(5-(3,5-dichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl) to the one-necked bottle -2-methyl-N-(2-oxo-2-(2,2,2-trifluoroethyl)amino)ethylbenzamide, 20 ml toluene and 0.18 g (1.80 mmol) triethylamine, Then add 0.15 g (1.35 mmol) of methoxyacetyl chloride, and heat up to reflux for 3 hours. Water was added to the reaction solution and extracted with ethyl acetate. The organic phase was dried over anhydrous magnesium sulfate, filtered, concentrated, and purified by column chromatography to obtain 0.27 g of a brown oil.
[0125] The NMR and mass spectrometry data of compound 19 are as follows:
[0126] 1 H NMR (600 MHz, DMSO- d 6 ) δ 8.75 (t, 1H), 7.82 (t, 1H), 7.68 (s, 1H),7.66 – 7.60 (m, 3H), 7.50 (d, 1H), 4.38 (d, 1H), 4.32 (s, 2H), 4.31 (d, 1H), 4.25 (s, 2H), 3.96 – 3.84 (m, 2H), 3.26 (s, 3H), 2.34 (s, 3H). ESI-MS, m / Z :626.22 [M-H] - .
