Procedure

1-chloroethyl chloroformate (12.8 mL, 0.104 mol) was added drop-wise via syringe to a stirred solution of 2-(1-Benzhydryl-azetidin-3-yloxy)-5-iodo-pyridine (23.03 g, 0.052 mol) in dichloromethane (250 mL) at ambient temperature. The resulting solution was stirred at ambient temperature for 3.5 hr, then methanol (250 mL) was added and the reaction mixture stirred at ambient temperature for 16 hr. The solvents were then removed in vacuo and the resulting solid residue was triturated with diethyl ether, filtered and then dried in vacuo to afford the title product as a cream-coloured solid (17.8 g, >quant yield). The crude product was used directly without further purification.
