Application of 112029-98-8, These common heterocyclic compound, 112029-98-8, name is (1-Methyl-1H-pyrazol-4-yl)methanol, 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.
Under a stream of nitrogen, cyanomethylenetributylphosphorane (0.06 mL) was dropped into a 0.2-mL toluene solution of the compound (30 mg) produced in Reference Example 20, and (1-methylpyrazol-4-yl)methanol (9.6 mg), and the mixture was stirred overnight at 100C. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography to obtain the title compound (7 mg) having the following physical property values. 1H-NMR (CDCl3): delta 1.26, 1.39-1.42, 1.68-1.85, 2.28-2.51, 2.55-2.65, 2.83-3.05, 3.87-4.01, 4.04-4.18, 4.89, 6.40, 6.72-6.79, 7.06-7.38, 7.41, 7.51, 8.77, 9.13.
The synthetic route of 112029-98-8 has been constantly updated, and we look forward to future research findings.
