Procedure

4.22 g of 3-[(5-chloro-2,3-dihydro-1H-inden-4-yl)oxy]-1-((diphenylmethyl))-azetidine were dissolved in 71 ml of 1,2-dichloroethane. 1.58 g of 1-chloroethyl chloroformate was added. The mixture was refluxed in an oil bath at 120° C. for 2.5 hours. After evaporation in vacuo the residue was refluxed in 71 ml of anhydrous methanol for 2 hours. Evaporation in vacuo gave a semi solid that was stirred with diethyl ether and filtered. The solid was recrystallized from ethanol/diethyl ether, yielding 1.57 g of 3-[(5-chloro-2,3-dihydro-1H-inden-4-yl)oxy]-azetidine hydrochloride, m.p. 188° C.
