A mixture of 4-amino-5-(4-phenoxyphenyl)-7-(tert-butyl)pyrrolo[2,3-d]-pyrimidine (0.20 g), N-chlorosuccinimide (80 mg) and dichloromethane (5 ml) was stirred at ambient temperature for 18 hours. The mixture was concentrated under reduced pressure and the residue was partitioned between ethyl acetate and water. The organic layer was separated, dried and evaporated to give an oil which was purified by flash column chromatography on silica using ethyl acetate/triethylamine (95:5) as the mobile phase. Appropriate fractions were collected, combined and evaporated to give 7-(tert-butyl)-6-chloro-5-(4-phenoxyphenyl)-7H-pyrrolo-[2,3-d]pyrimidin-4-ylamine, m.p. 136.8-137.8° C.
