(2-Chloro-9-methyl-9H-purin-6-yl)-(4-chloro-phenyl)-amine (3.58 g, 12.1 mmol) was dissolved in tetrahydrofuran (50 mL). Hydrazine monohydrate (26 mL, 536 mmol) was added and the reaction mixture was heated to reflux over night. The next day water was added and the resulting solid was collected by filtration, washed with water and dried to give (4-chloro-phenyl)-(2-hydrazino-9-methyl-9H-purin-6-yl)-amine (3.16 g, 90%) as a white crystalline compound.
