Electric Literature of 155377-19-8<\/a>, A common heterocyclic compound, 155377-19-8, name is Ethyl 3-(trifluoromethyl)pyrazole-4-carboxylate, molecular formula is C7H7F3N2O2, its 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

According to the procedure of Buchwald et al . (J. Org. Chem. 2004, 69, 5578), to a 50 mL sealed tube flushed with argon were added copper (I) iodide (0.02288 g, 0.1201 mmol) , K2CO3 (0.6972 g, 5.045 mmol), and ethyl 3- (trifluoromethyl) -IH- pyrazole-4-carboxylate (0.500 g, 2.402 mmol). ( IS, 2S) -N1,N2- Dimethylcyclohexane-1, 2-diamine (0.06834 g, 0.4805 mmol) and 2-bromophenol (0.3343 mL, 2.883 mmol) were then added along with 3 mL of toluene (degassed under argon) . The tube was sealed and heated to 1100C overnight, then cooled to room temperature and the mixture was filtered through celite to remove the solid. The filtrate was concentrated under vacuum and the residue was purified by chromatography (10% ether\/DCM) to give ethyl 1- (2-hydroxyphenyl) -3- (trifluoromethyl) -IH- pyrazole-4-carboxylate (0.660 g, 91%) as a solid: 1H NMR (400 MHz, CDCl3) delta 1-40 (t, 3H, J = 7.0 Hz), 4.39 (q, 2H, J = 7.0 Hz), 7.00 (m, IH), 7.16 (m, IH), 7.31 (m, IH), 7.42 (m, .1H), 8.56 (m, IH).<\/p>\n

The synthetic route of 155377-19-8 has been constantly updated, and we look forward to future research findings.<\/p>\n
