Reaction Steps

To a solution (1-pyrimidin-4-yl-piperidin-4-yl)-carbamic acid tert-butyl ester (1.00 g, 3.59 mmol) in dichloromethane (16 mL) was added HCl (2 M in diethylether, 8.98 mL, 18.0 mmol) and the reaction mixture was stirred at room temperature for 4 hours. The mixture was then diluted with NaOH (2 N) at 0° C. and extracted with dichloromethane. The combined organic extracts were then dried over sodium sulfate and filtered to afford the title compound (511 mg, 80%) as a light yellow solid.
