Participants

Reaction Steps

0.6 g of 5-(4-benzyloxy-3-methoxyphenyl)-7-[3-(2-(1-imidazolyl)ethoxy)phenyl]-4-amino-pyrrolo[2,3-d]pyrimidine is hydrogenated in a hydrogen atmosphere at normal pressure and about 50° C. for 6 h in 20 ml of THF and 10 ml of ethanol in the presence of 0.2 g of 5% palladium/carbon. After filtration through Celite and crystallization of the residue from methylene chloride, 5-(4-hydroxy-3-methoxyphenyl)-7-[3-(2-(1-imidazolyl)ethoxy)phenyl]-4-aminopyrrolo[2,3-d]pyrimidine having an m.p. of 190° C. is obtained.
