1-methyl-3-((methylamino)methyl)-1H-pyrazole-5-nitrile synthesis method

The invention belongs to the technical field of medicine and relates to a 1-methyl-3-((methylamino)methyl)-1H-pyrazole-5-nitrile synthesis method. Diethyl oxalate and acetone are easily acquirable andused as starting materials to obtain 1-methyl-3-((methylamino)methyl)-1H-pyrazole-5-nitrile through 7-step reaction including condensation, cyclization, methylation, amidation, oxidation, brominationand amination. By adoption of the method, preparation of 1-methyl-3-((methylamino)methyl)-1H-pyrazole-5-nitrile which is a key intermediate of antitumor drug lorlatinib (PF-06463922) is realized, thetotal yield reaches 5.7% or above, and simplicity in operation, convenience in aftertreatment, short time consumption and low cost are realized while industrialization can be realized beneficially. The intermediate and 5-fluoro-3-methyl isobenzofuran-1(3H)-ketone are subjected to reaction steps including ammonolysis, substitution, coupling, chiral resolution and the like to finally synthesize lorlatinib, and a novel method is provided for synthesis of the antitumor drug lorlatinib.
