Procedure

To a solution of tert-butyl 3-(pyridin-4-ylmethoxy)azetidine-1-carboxylate (313 mg, 1.18 mmol; which may be prepared as described in Step 3) in diethyl ether (4 mL) at 0° C. was added HCl 2N in diethyl ether (12 mL). The reaction mixture was stirred for 1 h then mixture was filtered. The resulting solid was rinsed with diethyl ether and collected to give the title compound as a white solid (155 mg, 65%).
