Procedure

To a stirred solution of (5′-chloro-4-methyl-3,4,5,6-tetrahydro-2H-(1,2′)bipyridinyl-4-yl)-carbamic acid benzyl ester (0.060 g, 0.17 mmol ) in acetonitrile (1.0 mL) at room temperature was added iodotrimethysilane (0.04 mL, 0.25 mmol). The reaction mixture was stirred at 50° C. for 30 minutes, concentrated under reduced pressure, and purified by flash chromatography with 3% methanol in dichloromethane to provide titled compound. MS (CI) m/z 226 (M+1)+.
