Application of 112029-98-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 112029-98-8 name is (1-Methyl-1H-pyrazol-4-yl)methanol, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
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. 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.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, (1-Methyl-1H-pyrazol-4-yl)methanol, and friends who are interested can also refer to it.
