To a stirred suspension of 200 mg (0.66 mmol) 5-bromo-4-furan-2-yl-6-methanesulfinyl-pyrimidin-2-ylamine in 5 ml dioxane was added 0.16 ml (1.46 mmol) benzylamine and the mixture heated at 100° C. for 2 hour. The reaction mixture was then concentrated in vacuo. Chromatography (ethyl acetate) followed by trituration in ether/hexane afforded 162 mg (71%) N4-benzyl-5-bromo-6-furan-2-yl-pyrimidine-2,4-diamine as a white crystalline solid. EI-MS m/e (%): 346 (M{81Br}+, 50), 344 (M{79Br} +51), 265 (46), 106 (100), 91 (61).
