Reaction Steps

To a stirred solution of 260 mg (0.80 mmol) trifluoromethanesulfonic acid 2-amino-5-fluoro-6-furan-2-yl-pyrimidin-4-yl ester in 15 ml DME were added 0.27 ml (2.80 mmol) 2-(hydroxymethyl)pyridine and 0.12 ml (0.80 mmol) DBU and the mixture heated at 50° C. for 2 hour. The reaction mixture was then concentrated in vacuo. Chromatography (ethyl acetate) followed by trituration in dichloromethane/ether/hexane afforded 22 mg (10%) 5-fluoro-4-furan-2-yl-6-(pyridin-2-ylmethoxy)-pyrimidin-2-ylamine as a white crystalline solid. EI-MS m/e (%): 286 (M+, 100), 107 (52).
