Reaktionsschritte

A mixture of 2 g of 3-(3-tetrahydropyr-2-yloxyprop-1-yn-1-yl)-4-hydroxy-6-pivaloylaminopyrrolo[2,3-d]pyrimidine, 40 ml of methanol, 20 ml of chloroform, 40 mg of 5% palladium on barium sulfate, and 40 mg of synthetic quinoline is stirred under 1 atmosphere hydrogen pressure for 40 min. The solvent then is removed by evaporation and the residue diluted with methylene chloride. The methylene chloride solution is filtered through silica gel with 2% methanol in methylene chloride to remove catalyst and the filtrate then concentrated to give an oil which upon adding ether yields 3-(3-tetrahydropyr-2-yloxyprop-1-en-1-yl)-4-hydroxy-6-pivaloylaminopyrrolo[2,3-d]pyrimidine which can be further purified through column chromatography eluting with ethyl acetate and recrystallization using ethyl acetate.
