Procedure

To a stirred solution of 4-[5-fluoro-3-[4-(2-methylimidazol-1-yl)benzyloxy]-phenyl]-3,4,5,6-tetrahydro-2H-pyran-4-carboxamide (Example 5) in THF (10 ml) was added phosphorus pentasulfide (236 mg, 0.53 mmol) and sodium bicarbonate (176 mg, 2.1 mmol). The resulting mixture was heated at 40° C. for 4 hr. The mixture was concentrated in vacuo. To the residue was added water (100 ml) and the mixture was extracted with dichloromethane (2×100 ml). The combined organic extracts were dried over sodium sulfate and concentrated in vacuo. The residue was purified on column chromatography (LiChropprep --NH2) and then by p-TLC eluting with dichloromethane-methanol (10:1) to afford 38 mg of the titled compound as white solids.
