Procedure

2,6-Dichloro-9-methyl-9H-purine (1.40 g, 6.93 mmol) was dissolved in acetonitrile (25 mL). Triethylamine (4.81 mL, 34.5 mmol) and cyclohexylamine (0.79 mL, 6.90 mmol) were added and the reaction mixture was stirred at 50° C. over night. The reaction mixture was cooled to room temperature and concentrated in vacuo. Water was added followed by extraction with ethyl acetate. The combined organic phases were dried over magnesium sulphate, filtered and concentrated in vacuo to give (2-chloro-9-methyl-9H-purin-6-yl)-cyclohexyl-amine (1.5 g, 82%) as a crystalline compound.
