Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 345637-71-0, name is 2-(5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetic acid, A new synthetic method of this compound is introduced below., name: 2-(5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetic acid<\/a><\/p>\n

d) Preparation of 2-(2-chloro-6-fluoro-phenyl)-N-(4-{1-[2-(5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetyl]-piperidin-4-yl}-thiazol-2-yl)-acetamide (compound I.as.001) To a solution of 2-(2-chloro-6-fluoro-phenyl)-N-(4-piperidin-4-yl-thiazol-2-yl)-acetamide hydrochloride (0.43 g, 1.1 mmol) in 15 ml of N,N-dimethylformamide are added at 0 C. ethyl(diisopropyl)amine (0.35 g, 2.7 mmol), (5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetic acid (0.25 g, 1.2 mmol) and benzotriazol-1-yloxy-tris(dimethylamino)-phosphonium hexafluorophosphate (0.53 g, 1.2 mmol). The reaction mixture is stirred for 16 h at room temperature and then evaporated. The remainder taken up with ethyl acetate, extracted with 1 N aqueous sodium bicarbonate solution, 0.5 N aqueous hydrochloric acid and brine, dried over sodium sulfate and evaporated. The residue is purified by column chromatography on silica gel (cyclohexane\/ethyl acetate 3:1) to give 2-(2-chloro-6-fluoro-phenyl)-N-(4-{1-[2-(5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetyl]piperidin-4-yl}-thiazol-2-yl)-acetamide (compound I.as.001) as white crystals. m.p. 249-251 C. 1H-NMR (400 MHz, CDCl3): delta=1.62 (dd, 2H), 2.04 (t, 2H), 2.30 (s, 3H), 2.71-2.88 (m, 2H), 3.22 (t, 2H), 3.96-4.03 (m, 3H), 4.60 (d, 1H), 4.99 (q, 2H), 6.32 (s, 1H), 6.53 (s, 1H), 7.11 (t, 1H), 7.28-7.33 (m, 2H), 8.66 (s, 1H). MS: m\/z=544 (M+1).<\/p>\n
