[0032]

[0033]3,3-Dimethyl-1-(1,2,4-triazol-1-yl)-1-bromo-2-butanone and phenylthiourea compounds are fed in a molar ratio of 1:1, in ethanol Heating to reflux reaction. After the reaction was completed, the solvent was distilled off under reduced pressure, washed with ethyl acetate, filtered, and dried to obtain 4-tert-butyl-2-phenylamino-5-(1,2,4-triazol-1-yl)thiazole hydrobromide Salt; hydrobromide was neutralized with ammonia water, extracted with ethyl acetate, distilled under reduced pressure, and recrystallized from ethanol to obtain 4-tert-butyl-2-phenylamino-5-(1,2,4-triazol-1-yl ) Thiazole, melting point 186-188°C. 1 H NMR (CDCl 3 , 400MHz), δ: 1.17(s, 9H, 3×CH 3 ), 1.83 (brs, 1H, NH), 7.10~7.40 (m, 5H, C 6 h 5 ), 8.10(s, 1H, C 2 h 2 N 3 3-H), 8.26(s, 1H, C 2 h 2 N 3 5-H).

Embodiment 24

[0034] Preparation of Example 24-tert-butyl-2-(3-methylanilino)-5-(1,2,4-triazol-1-yl)thiazole

[0035]

[0036] According to the method of Example 1, react 9.0h; Obtain 4-tert-butyl-2-(3-methylanilino)-5-(1,2,4-triazol-1-yl)thiazole; Melting point 98~ 100°C; 1 H NMR (CDCl 3 , 400MHz), δ: 1.16(s, 9H, 3×CH 3 ), 2.36(s, 3H, CH 3 ), 6.94 (d, J=8.0Hz, 1H, C 6 h 4 4-H), 7.12(d, J=6.4Hz, 1H, C 6 h 4 6-H), 7.13(s, 1H, C 6 h 4 2-H), 7.25(t, 1H, J = 7.2Hz, 1H, C 6 h 4 5-H), 8.08(s, 1H, C 2 h 2 N 3 3-H), 8.24(s, 1H, C 2 h 2 N 3 5-H).

Embodiment 34

[0037] Preparation of Example 34-tert-butyl-2-(4-methylanilino)-5-(1,2,4-triazol-1-yl)thiazole

[0038]

[0039] According to the method of Example 1, react 4.0h; Obtain 4-tert-butyl-2-(4-methylanilino)-5-(1,2,4-triazol-1-yl)thiazole; Melting point 147~ 150°C; 1 H NMR (CDCl 3 , 400MHz), δ: 1.17(s, 9H, 3×CH 3 ), 2.34(s, 3H, CH 3 ), 7.18 (d, J=8.8Hz, 2H, C 6 h 5 3,5-H), 7.22 (d, J=8.8Hz, 2H, C 6 h 5 2,6-H), 8.08(s,1H,C 2 h 2 N 3 3-H), 8.24(s, 1H, C 2 h 2 N 3 5-H).

Abstract

The invention discloses 4-alkyl-2-arylamino-5-(1,2,4-triazole-1-group) thiazole and salts thereof shown in a formula I, wherein R is selected from H, alkyl groups of C1-C2 and straight-chain alkyl groups or branched-chain alkyl groups of C3-C4; X1, X2, X3, X4 and X5 are selected from hydrogen, alkyl groups of C1-C2, hydroxide group, methoxy group, oxyethyl group, trifluoromethyl, fluorine, chlorine, bromine, nitryl, amino group, acetyl amino group, methanesulfamide, ethoxycarbonyl or carboxyl; and the salts of the 4-alkyl-2-arylamino-5-(1,2,4-triazole-1-group) thiazole are selected from hydrochloride, hydrobromide, nitrate, sulfate, phosphate, mesylate, p-toluene sulfonate, tartrate, lactate or malate. The 4-alkyl-2-arylamino-5-(1,2,4-triazole-1-group) thiazole is applied to preparation of medicaments for resisting cervical cancer or lung neoplasms.

Description

technical field [0001] The present invention relates to a class of novel compounds and their preparation methods and applications, specifically 4-alkyl-2-arylamino-5-(1,2,4-triazol-1-yl)thiazoles and their preparation methods and as preparation Application of anti-cervical cancer or human lung cancer drugs. Background technique [0002] Azole heterocyclic derivatives have always been paid attention to by drug and pesticide workers because of their good biological activity, high drug efficacy, wide bactericidal spectrum, and good systemic property [Comperhensive Heterocylic Chemistry. Pergamon Oxford, 1983, 5: 733-735], and triazoles are one of the more influential ones. The bactericidal mechanism of triazole fungicides is to affect the formation of fungal cell walls by hindering the biosynthesis of fungal ergosterol, and have good control effects on most fungal diseases that endanger crop growth. Triazole fungicides also have certain plant growth regulating activity [Pesti...
