Reaction Steps

4-[9-(2-Cyanobenzyl)-9H-purin-6-yl]-piperazine-1-carboxylic acid t-butyl ester (0.419 g) was suspended in N,N-dimethylformamide (80 mL), and then N-chlorosuccinimide (0.160 g) was added. This was stirred at room temperature for 72 hours. N-chlorosuccinimide (0.160 g) was added again, and this was then heated at 60° C. for 18 hours. Ethyl acetate (200 mL) and water (100 mL) were then added, and the organic layer was washed twice with 50 mL of water and then once with 5 mL of saturated aqueous sodium chloride solution. This was then dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure, and then the residue was purified by silica gel chromatography. The dichloromethane:ethyl acetate 7:3 fraction gave the title compound (0.100 g).
