実験手順

To 40 mL of phosphorus oxychloride and 3 mL. of dimethylaniline is added 2.2 g of crude 4-hydroxy-3-methyl-6-methylmercaptopyrazolo[3,4-d]pyrimidine. The solution was refluxed for 30-60 minutes when all the solid had dissolved. The excess phosphorus was removed under reduced pressure. The residue was poured with vigorous stirring onto a mixture of ice water. After ten minutes, the aqueous solution was extracted with ether. The ether solution was washed with cold water and dried with anhydrous sodium sulfate. The product was obtained after filtering and removing ether under reduced pressure. 215.0 (M+1)+.
