摘要: A synthesis method for an aminopyrimidine FAK inhibitor compound, relating to the field of pharmaceutical synthesis. In the synthesis method, R 1 is hydrogen or a carboxylic acid protecting group, R 2 is selected from C 1 -C 6 alkyl or C 1 -C 6 deuterated alkyl, R 3 and R 4 are each independently selected from hydrogen or deuterium, and R 5 is selected from C 1 -C 6 alkyl or C 1 -C 6 deuterated alkyl. The synthesis method is simple to operate, and has low costs. The product prepared can obtain a high total yield (≥ 66%) and a high purity (≥ 99%), and the product yield and purity are superior to those in the prior art (in the prior art, the total yield is about 11%, and the purity is 99%). The synthesis method achieves excellent effects, can also successfully prepare a final product on kilogram scale, and is suitable for industrial production, having a good application prospect.
