Paragraph 0059-0062, (2017/07/12)
The invention relates to a method for synthesizing an isoquinolone derivative of formula (III) as an anti-cancer inhibitor intermediate. The method comprises the step: in a reaction solvent, in the presence of a catalyst, a nitrogen-containing ligand, an acid additive and 4-dimehtyl aminopyridine, performing a reaction on a compound of formula (I) as shown in the specification and a compound of formula (II) as shown in the specification, and after posttreatment, obtaining a compound of formula (III) as shown in the specification, wherein in the formulae, R1 is C1-C6 alkyl; R2 is H, halogen, C1-C6 alkyl or C1-C6 alkoxy; or R2 and substituted phenyl form naphthyl; and M is an alkali metal element. By adopting the method, due to comprehensive selection and mutual action of a reaction substrate, the catalyst, the nitrogen-containing ligand, the acid additive, the 4-dimehtyl aminopyridine and the solvent, the substrate range can be widened, a target product of high yield can be obtained, an intermediate of relatively rich diversities can be provided for synthesis of the compounds and development and synthesis of anti-cancer inhibitor medicines, and good research values and application potential can be achieved.
