NAI (2.27 g, 16.0 mmol) and Me3Sicl (2.02, 16.0 mmol) were stirred in CH3CN (70 mL) at 0° C. (Phenyl)-pyrid-4-yl-(thien-2-yl)methanol (0.534 g, 2.00 mmol (Example 93)) was added at 0° C. and the resulting solution was stirred over night at room temperature. Na2S2O3 (sat., 20 mL) was added and the two phase system was stirred 5 minutes. The phases were separated and the organic layer was dried (MgSO4), filtered and evaporated. The resulting crystals were dissolved in CH2Cl2 (30 mL), the solution was washed with NaHCO3 (30 mL, sat.) and H2O (30 mL), dried (MgSO4) and evaporated yielding 0.41 g which was recrystallized in diisopropyl ether giving 0.22 g (43.8%) of the pure title compound.
