852227-86-2, 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. 852227-86-2 name is 5-(Chloromethyl)-1,3-dimethyl-1H-pyrazole, 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.
A mixture of 3-[(1 -methylpyrazol-4-yl)methyl]-2,4-dioxo-N-[1 – (trideuteriomethyl)cyclopropyl]- 1H -quinazoline-6-sulfonamide (100 mg, 0.25 mmol), 5- (chloromethyl)-1 ,3-dimethyl- 1H -pyrazole (37 mg, 0.25 mmol), potassium carbonate (70 mg, 0.51 mmol) and potassium iodide (42 mg, 0.25 mmol) in DMF (2 mL) was heated with agitation in the microwave at 80 C for 30 minutes. The solvent was removed in vacuo and the residue purified by prep HPLC (high pH) to give the desired product (68 mg, 0.136 mmol, 53%) as a white powder
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-(Chloromethyl)-1,3-dimethyl-1H-pyrazole, and friends who are interested can also refer to it.
