Adding a certain compound to certain chemical reactions, such as: 52222-73-8, name is 4-(Trifluoromethyl)-1H-pyrazole, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 52222-73-8, Computed Properties of C4H3F3N2<\/a><\/p>\n

Example 29 2-[1-(2-Fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-5,5-dimethyl-4-[4-(trifluoromethyl)-1H-pyrazol-1-yl]-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one Under argon atmosphere, 200 mg (purity 62%, 0.24 mmol) of 2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-4-iodo-5,5-dimethyl-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one (example 15A) was suspended in 2.5 ml of absolute acetonitrile, and 656 mg (4.82 mmol) of 4-(trifluoromethyl)-1H-pyrazole, 157 mg (0.48 mmol) of caesium carbonate, 7 mg (0.05 mmol) of copper(I) oxide and 26 mg (0.19 mmol) of 2-hydroxybenzaldehyde-oxime were added. The mixture was heated in the microwave for 1 h at 200 C. The reaction solution was filtered and purified by preparative HPLC (eluent: acetonitrile\/water with 0.1% formic acid, gradient 20:80?100:0). 85 mg (63% of theor.) of the target compound was obtained. LC-MS (method 1): Rt=1.33 min; MS (ESIpos): m\/z=523 [M+H]+ 1H-NMR (400 MHz, DMSO-d6): delta [ppm]=1.56 (s, 6H), 5.91 (s, 2H), 7.15 (t, 1H), 7.20-7.25 (m, 2H), 7.34-7.39 (m, 1H), 7.52 (dd, 1H), 8.51 (s, 1H), 8.71 (dd, 1H), 8.92 (dd, 1H), 9.30 (s, 1H), 11.99 (s, 1H).<\/p>\n
