Participants

Reaction Steps

To 100 mg of 4-chloro-2-methylthiopyrrolo[2,3-d]pyrimidine was added 2 ml of cyclopentylamine. The solution was heated at reflux under nitrogen for 2 hours. The resulting dark oil was purified by chromatography on 30 g of Sephadex LH-20, elution with H2O and then with increasing concentrations of EtOH up to 40% EtOH. The appropriate fractions were combined and evaporated to dryness and the solid residue was crystallized from EtOH/H2O to afford tan crystals of product, yield 50 mg (40%), m.p. 190°-191° C.
