1.35 g of 5-(3-benzyloxyphenyl)-7-[3-(3-(1-imidazolyl)propoxy)phenyl]-4-aminopyrrolo[2,3-d]-pyrimidine are hydrogenated in a hydrogen atmosphere at normal pressure and about 40° C. for 16 h in 30 ml of methanol in the presence of 0.3 g of 5% palladium/carbon. After filtration through Celite, the solvent is stripped off and the residue is slurried in ether, filtered, slurried again in EA, filtered and dried. 5-(3-Hydroxyphenyl)-7-[3-(3-(1-imidazolyl)propoxy)phenyl]-4-aminopyrrolo[2,3-d]pyrimidine having an m.p. of 120°-122° C. is obtained.
