Procedure

To a solution of 4-cyano-4-[5-fluoro-3-[4-(2-methylimidazol-1-yl)phenylthio ]phenyl]-3,4,5,6-tetrahydro-2H-pyran (Example 25, 1.71 g, 4.36 mmol) in tert-butanol (20 ml) was added powdered potassium hydroxide (85%, 860 mg, 13 mmol). The resulting mixture was heated at reflux temperature for 4 h, cooled and concentrated in vacuo. Water (50 ml) was added and the precipitates were collected by filtration and washed with 50 ml of ethyl acetate. After drying in vacuo, 560 mg (31%) of the titled compound was obtained as a yellow powder.
