Procedure

A solution of (±)-cis-4-(-2-Amino-6-chloro-9H-purin-9-yl)-2-cyclopentene-1-methanol from Example 4 (0.53 g, 2 mmol) and cyclobutylamine (1.387 g, 19.5 mmol) in methanol (15 mL) was heated at 70°-75° C. (oil bath) for 29 hours. After cooling to room temperature, 2 mL of 1.0N NaOH was added. The solution was concentrated and the residue chromatographed on silica gel. Title compound was eluted with 5% methanol-chloroform as colourless foam which solidified to white powder in acetonitrile (454 mg, 75.7%), m.p. 181°-183° C.
