Procedure

To a solution of 2-[4-(1-benzhydryl-azetidin-3-yl)-piperazin-1-yl]-pyrimidine (2.03 g, 5.27 mmol) in CH2Cl2 (20 mL) was added 1-chloroethyl chloroformate (1.704 mL, 15.79 mmol) at 0° C. under N2. The resulting mixture was stirred at 0° C. for 90 min and then methanol (4 mL) was added. The resulting mixture was refluxed for 1 h, then cooled. Diethyl ether (40 mL) was added to the resulting mixture. The solid was filtered and dried to yield 2-(4-azetidin-3-yl-piperazin-1-yl)-pyrimidine, which was used in the next step without further purification.
