Embodiment 1
[0027] Example 1 Preparation of 1-(4-nitrophenyl)-3-phenyl-3-(4-chloroanilino)-1-acetone oxime
[0028]
[0029] Add 1.06 g (0.01 mol) of benzaldehyde, 1.28 g (0.01 mol) of 4-chloroaniline and 18 ml of absolute ethanol in the reaction flask, stir at room temperature for 10 minutes, then add 1.65 g (0.01 mol) of 4-nitroacetophenone And catalytic amount of concentrated hydrochloric acid, stirred at room temperature; the precipitated solid was filtered by suction and washed with absolute ethanol. The obtained solid was suspended in 20ml ethanol and washed with saturated NaHCO 3 The aqueous solution was neutralized to alkaline, filtered with suction, and the filter cake was washed with a small amount of absolute ethanol. The crude product was recrystallized in a mixed solvent of ethanol / water (volume ratio 1:1) to obtain 3.43 g of a light yellow powder solid, with a yield of 83%.
[0030] 1.9 grams (5 mmol) of the above-mentioned solid and 20 ml of ethanol were added to the re...
Embodiment 2
[0031] Example 2 Preparation of 1-(4-methylphenyl)-3-(2-thienyl)-3-(4-chloroanilino)-1-acetone oxime
[0032]
[0033] The operation process is the same as in Example 1, except that benzaldehyde is replaced by 2-thiophene formaldehyde, and 4-nitroacetophenone is replaced by 4-methylacetophenone to obtain white crystals with a yield of 85.6%; mp117~119°C; 1 H-NMR (400MHz, CDCl 3 )δ: 7.44(d, 2H, J=8.4Hz), 7.19(d, 2H, J=8Hz), 7.16(d, 1H, J=4.4Hz), 6.99(m, 3H), 6.92(t, 1H , J=3.6Hz), 6.39(d, 2H, J=8.4Hz), 4.89(dd, 1H, J=4.4Hz), 3.69(dd, 1H, J 1 =13.6Hz,J 2 =10Hz), 3.11(dd,1H,J 1 =13.6Hz,J 2 =4.4Hz), 2.38(s, 3H); ESI-MS m / z: 404.2(M + +H+MeOH).
Embodiment 3
[0034] Example 3 Preparation of 1-(4-methylphenyl)-3-phenyl-3-(4-chloroanilino)-1-acetone oxime
[0035]
[0036] The operation process is the same as in Example 1, except that 4-nitroacetophenone is replaced by 4-methylacetophenone to obtain light yellow crystals with a yield of 93.4%; mp156~158°C; 1 H-NMR (400MHz, CDCl 3 )δ: 7.48(d, 2H, J=8.4Hz), 7.38(d, 2H, J=6.8Hz), 7.32(t, 2H, J=7.2Hz), 7.26~7.20(m, 3H), 6.93( d, 2H, J=8.8Hz), 6.28(d, 2H, J=9.2Hz), 4.55(dd, 1H, J 1 =10.4Hz,J 2 =4Hz), 3.59(dd,1H,J 1 =13.6Hz,J 2 = 10.4Hz), 2.97(dd, 1H, J 1 =13.8Hz,J 2 =4Hz), 2.38(s, 3H); ESI-MS m / z: 365.9(M + +H).
