Procedure
To a stirred solution of 335 mg (0.95 mmol) trifluoro-methanesulfonic acid 2-amino-6-furan-2-yl-5-nitro-pyrimidin-4-yl ester in 20 ml dioxane was added 1.03 ml (9.46 mmol) benzylamine and the mixture heated at reflux for 1 hour. The reaction mixture was then concentrated in vacuo. Chromatography (ethyl acetate) followed by recrystallisation from ether/hexane afforded 230 mg (78%) N4-benzyl-6-furan-2-yl-5-nitro-pyrimidine-2,4-diamine as a yellow crystalline solid. ES-MS m/e (%): 312 (M+H+, 100).
