Procedure
Add trifluoroacetic acid (5 mL) to a solution of tert-butyl N-[2-[8-(2-chlorophenyl)-2-methyl-6-(4-methylpiperazin-1-yl)purin-9-yl]ethyl]carbamate (0.51 g, 0.001 mol) in dichloromethane (5 mL) at 0° C. Allow the reaction to warm to room temperature and stir for 2 h. Quench the reaction mixture with saturated aqueous sodium bicarbonate solution and then extract with dichloromethane. Dry the organic layer over anhydrous sodium sulfate, filter, and concentrate to give 2-[8-(2-chlorophenyl)-2-methyl-6-(4-methylpiperazin-1-yl)purin-9-yl]ethanamine (0.39 g). ES/MS m/z 386 (M+1).
