Procedure

To a suspension of 3 g of 3-[(2,3-dihydro-1H-inden-4-yl)oxy]-1-(diphenylmethyl)-azetidine hydrochloride in 250 ml ethanol were added 600 mg of palladium hydroxyde on carbon powder and the mixture was hydrogenated in a Parr apparatus at 60 psi during 16 hours. After removal of the catalyst and evaporation of the solvent in vacuo the residue was washed several times with diethyl ether and decanted to remove the diphenylmethane formed. The remaining solid was crystallized from ethanoudiethyl ether, yielding 1.27 g of 3-[(2,3-dihydro-1H-inden-4-yl)oxy]-azetidine hydrochloride, m.p. 65° C.
