Procedure

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. MS (CI) m/z 220 (M+1)+; 1H NMR (300 MHz, DMSO-d6) δ ppm 8.89 (d, 2H), 7.74 (d, 2H), 4.04 (m, 2H, NH2), 3.42-3.25 (m, 4H), 1.77-1.45 (m, 4H), 1.42 (s, 3H).
