Procedure
6-Amino-9-benzyl-2-chloropurine (100 mg, 0.385 mmol) and aniline (359 mg, 3.85 mmol) in 1-butanol (10 ml) were refluxed on heating for 20 hours. The reaction mixture was condensed in vacuo. To the residue was added 5N aqueous sodium hydroxide and the mixture was extracted with chloroform. The organic layer was dried on sodium sulfate, filtered and the solvent in the filtrate was evaporated in vacuo. The residue was purified with silica gel chromatography (2% methanol/chloroform) to give the subject compound (108 mg, yield 89%).
