Reference of 128694-63-3<\/a>,Some common heterocyclic compound, 128694-63-3, name is 1-Methyl-3-(trifluoromethyl)-1H-pyrazole-5-carboxylic acid, molecular formula is C6H5F3N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

Step 1: l-Methyl-3-(trifluoromethyl)-lH-pyrazol-5-yl] methanol Borane (1M in THF; 9.0 mL, 9.0 mmol) was added to a solution of l-methyl-5- (trifluoromethyl)pyrazole-3-carboxylic acid (350 mg, 1.8 mmol) in THF (10 mL) at rt. The mixture was stirred was stirred for 3 hours. It was then cooled to 0 C and quenched with water. The mixture was extracted with EtOAc (3x) and the combined organic layers were washed with brine, dried over Na2SC>4, filtered, and concentrated. The residue was purified on silica gel to afford [l-methyl-3-(trifluoromethyl)- lH-pyrazol-5-yi]methanol (188 mg; 58%) as a colorless oil. LCMS (FA): m\/z = 18l (M+H).<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Methyl-3-(trifluoromethyl)-1H-pyrazole-5-carboxylic acid, its application will become more common.<\/p>\n
