Procedure

To a stirred suspension of 500 mg (2.24 mmol) 4-furan-2-yl-6-methanesulfinyl-pyrimidin-2-yl-amine in 20 ml DME was added 0.50 ml (4.48 mmol) 2-(2-hydroxyethyl)pyridine and 0.84 ml (5.60 mmol) DBU and the mixture heated at 100° C. for 72 hours. The reaction mixture was then cooled to room temperature and partitioned between water and dichloromethane. The organic phase was dried over sodium sulfate and concentrated in vacuo. Chromatography (ethyl acetate) followed by trituration in ether afforded 220 mg (35%) 4-furan-2-yl-6-(2-pyridin-2-yl-ethoxy)-pyrimidin-2-ylamine as a white crystalline solid. ES-MS m/e (%): 283 (M+H+, 100).
