Reaction Steps

6-Chloro-9-isopropyl-9H-purin-2-ylamine (2.7 g, 12.8 mmol), CuI (1.2 g, 13.4 mmol), I2 (3.3 g, 12.8 mmol), isoamyl nitrite (10.6 mL), and CH2I2 (5.3 g, 39.3 mmol) in THF (60 mL) were heated at reflux for 75 min. The mixture was cooled to rt, filtered through Celite, and adsorbed onto silica gel. Purification by chromatography (60% EtOAc/hexane) yielded an off-white solid (13.4 g, 54%): MS [M+H]+ 323; m.p.104° C.
