Sodium sulfate decahydrate → N-(3-Thienylmethyl)-9H-purin-6-amine

Participants

Reaction Steps

A suspension of 20 g (0.082 mole) of 6-(3-thenoylamino)-purine in 1 l of absolute tetrahydrofuran is added dropwise to a stirred suspension of 6.5 g (0.17 mole) of lithium aluminum hydride in 350 ml of absolute tetrahydrofuran at 80° C. After 3 hours, the excess hydride is decomposed with sodium sulfate decahydrate, the residue is filtered off, the filtrate is brought to dryness and the resulting oily crystal slurry is crystallized several times from tetrahydrofuran. 6-(3-Thienylmethylamino)-purine is obtained in a yield of 25%.
