Paragraph 0075-0081, (2019/07/04)
The invention provides a preparation method of cangrelor key intermediate compound d. The target compound is prepared by subjecting a compound a as a start material to formyl protection, carrying outN-alkylation and carrying out deprotection reaction. The preparation method has the advantages of short route, good operational simplicity, high yield, low cost and low three-wastes. The invention also provides novel intermediate compounds b and c for preparing the compound d and a preparation method of the compounds b and c.

Paragraph 0052; 0053; 0054, (2018/09/13)
The invention relates to a method for preparing a cangrelor key intermediate by utilizing diaminomercaptopyrimidine. The method takes 4,6-diamino-2-mercaptopyrimidine as a starting raw material and comprises the following steps: firstly, adding trifluoropropyl under an alkaline condition to obtain an intermediate 1; then adding amino to obtain an intermediate 2; then adding a glycosidic bond into2-[(3,3,3-trifluoropropyl)sulfenyl]-9H-purine-6-amino to obtain an intermediate 4; then adding acetyl to obtain an intermediate 5; then adding a branch chain to obtain an intermediate 6; finally, carrying out hydrolytic acidification to obtain the cangrelor key intermediate. According to the method provided by the invention, a synthetic product is a light yellow or yellow solid; liquid chromatography and mass spectrometry, and a nuclear magnetic hydrogen spectrum are used and can be used for determining that the yellow solid is a cangrelor key intermediate pure product. The method has the advantages of low cost, high yield, moderate reaction condition and simple post-treatment, and has a relatively great industrialized potential.
