Abstract
A novel thiopyrano(4,3-d)pyrimidine derivative compound 1 was synthesized with methyl dimethyl 3,3'-thiodipropionate as starting material through five steps, including cyclization, chlorination, substitution with morpholine and coupling with 5-bromopyridin-2-amine through S uzuki reaction. And its structure was confirmed by 1 H NMR and MS. The total yield of the five steps was 18.6% (calculated from methyl dimethyl 3,3'-thiodipropionate).Compound 1 is an important intermediate in the design and synthesis of thiopyrano(4,3-d)pyrimidine derivatives small molecule inhibitors.Therefore, the synthesis of Compound 1 has an important significance in the the study of anticancer drugs.
