実験手順

Add methyl chloroformate (0.25 g, 0.0027 mol) to a solution of 2-[8-(2-chlorophenyl)-2-methyl-6-(4-methylpiperazin-1-yl)purin-9-yl]ethanamine (0.39 g, 0.0010 mol) and pyridine (4.0 mL) in dry dichloromethane (4 mL) at 0° C. Allow to warm to room temperature and stir for 2 hour. 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 a residue. Purify the residue on a silica gel column using dichloromethane:methanol (97:3) as eluent to afford methyl N-[2-[8-(2-chlorophenyl)-2-methyl-6-(4-methylpiperazin-1-yl)purin-9-yl]ethyl]carbamate (0.3 g). ES/MS m/z 444 (M+1).
