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. 119022-51-4, name is 1-Methyl-5-(trifluoromethyl)-1H-pyrazol-3(2H)-one, A new synthetic method of this compound is introduced below., Safety of 1-Methyl-5-(trifluoromethyl)-1H-pyrazol-3(2H)-one<\/a><\/p>\n

Example 2: Preparation of 2-(1 -methyl-5-trifluoromethyl-1 H-pyrazol-3-yloxy)-thiazole- 5-sulfonic acid (2-methoxy-pyridin-4-ylmethyl)-amide (Table I, example I-4) Example 2.1 : Preparation of 2-(1-methyl-5-trifluoromethyl-1 H-pyrazol-3-yloxy)-thiazole 1-Methyl-5-trifluoromethyl-1 H-pyrazol-3-ol (5.1 g) in dry DMF (50 ml) under nitrogen was treated at 00C with sodium hydride (0.82 g). After the initial effervescence ceased 2-bromothiazol (5 g) and Kl (4.4 g) were added. The mixture was stirred for 23 h at1400C, the solvent was removed by rotary evaporation and the residue was purified by flash column chromatography on silica gel (cyclohexan\/ethyl acetate) to yield the title compound as yellow oil (4.94 g). 1H-NMR (CDCI3): d= 3.98 (s, 3H), 6.6 (s, 1 H), 6.9 (s, 1 H), 7.3 ppm (s,1 H)<\/p>\n
