Reaction Steps

To a stirred solution (4-methyl-1-(pyridine-4-carbonyl)-piperidin-4-yl)-carbamic acid benzyl ester (0.085 g, 0.24 mmol ) in acetonitrile (2.0 mL) at room temperature was added iodotrimethysilane (0.06 mL, 0.36 mmol). The reaction mixture was stirred at 50° C. for 30 minutes and concentrated under reduced pressure. The solid residue was washed with acetone and filtered to provide titled compound.
