Reference of 143426-49-7<\/a>,Some common heterocyclic compound, 143426-49-7, name is (4-Pyrazol-1-yl-phenyl)methanol, molecular formula is C10H10N2O, 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

To a suspension of (4-(1H-pyrazol-1-yl)phenyl)methanol (22.5 g) in acetonitrile (500 mL) was added N-fluoro-N’-(chloromethyl)triethylenediamine bis(tetrafluoroborate) (108 g) at room temperature, and the mixture was stirred at 80C for 16 hr. The reaction solution was diluted with ethyl acetate, washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated. The residue was purified by silica gel chromatography (petroleum ether-ethyl acetate) to give the title compound (4.5 g). 1H NMR (400 MHz, CDCl3) delta 4.73 (2H, s), 7.45 (2H, d, J = 8.0 Hz), 7.57 (1H, d, J = 4.0 Hz), 7.61 (2H, d, J = 8.0 Hz), 7.80 (1H, d, J = 4.8 Hz).<\/p>\n

The synthetic route of 143426-49-7 has been constantly updated, and we look forward to future research findings.<\/p>\n
