The invention provides a method for preparing AZD-4547. The method comprises the following steps: (1) preparing a first intermediate 2-cyano-5-(3, 5-dimethoxyphenyl)-3-oxoethyl valerate; (2) preparinga second intermediate 5-[2-(3, 5-dimethoxyphenyl) ethyl]-1H-pyrazole-3-amine by taking the first intermediate as a raw material; and (3) in an alkali-containing organic solvent, carrying out a reaction on a third intermediate 4-((3S, 5R)-3, 5-dimethylpiperazinyl-1-yl) benzoyl chloride and the second intermediate to prepare the AZD-4547. The method has the advantages of accessible raw materials, simple technique, mild reaction conditions, convenient operation, high yield and low cost and can easily implement industrial production. The invention also provides an intermediate 2-cyano-5-(3, 5-dimethoxyphenyl)-3-oxoethyl valerate for preparing AZD-4547 and a preparation method thereof.

Paragraph 0037-0040, (2018/10/19)
The invention belongs to the field of medicine chemical industries, and particularly relates to a new synthetic process for 5-[2-(3,5-dimethoxyphenyl)ethyl]-1H-pyrazole-3-amine of an AZD4547 key intermediate. The synthetic process comprises the following steps: using 2-(3,5-dimethoxyphenyl) ethylpropionate as a starting raw material, in the presence of a basic catalyst and an organic solvent, reacting with acetonitrile, enabling an obtained product to perform cyclization with hydrazine hydrate in the presence of concentrated sulfuric acid, to obtain a target product of the 5-[2-(3,5-dimethoxyphenyl)ethyl]-1H-pyrazole-3-amine. Compared with a current technology, the provided synthetic process for the 5-[2-(3,5-dimethoxyphenyl)ethyl]-1H-pyrazole-3-amine is capable of greatly shortening thereaction time, enabling the yield of the product to be higher, wherein a process of purifying the intermediate does not exist between two steps of the reactions, shortening a reaction period, and reducing the wastewater discharge, and suitable for the industrialized mass production.
