Reaction Steps

3.2 g. Phenyl glycidyl ether and 5.9 g. 4-(2-aminoethylamino)-pyrazolo[3,4-d]pyrimidine are stirred in 100 ml. methanol for 24 hours at ambient temperature and then for 5 hours at 80° C. Solid material (0.8 g.) is then filtered off with suction, the filtrate is evaporated and the yellowish oil obtained is dissolved in methylene chloride-methanol (9:1 v/v) and purified chromatographically in the manner described in Example 50. There is obtained 1.8 g. (26% of theory) of the desired product in the form of colorless crystals; m.p. 142°-144° C., after recrystallization from ethanol.
