Procedimiento

Sodium hydride (0.24 g, 5.98 mmol) was suspended in tetrahydrofuran (19.9 mL) and cooled to 0° C. Tetrahydro-2H-thiopyran-4-ol (0.24 g, 1.99 mmol) was added and the reaction was stirred for 30 minutes. 2-Bromo-6-(bromomethyl)pyridine (Example 190, Step 1) (0.5 g, 1.99 mmol) was added and the reaction was warmed to and maintained at ambient temperature overnight. The reaction was diluted with ethyl acetate, quenched slowly with water, the layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layers were dried over magnesium sulfate, filtered and concentrated. The crude mixture was purified by silica gel chromatography to yield the title compound.
