Reaction Steps

A suspension of 8-benzyl-2-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}-3-oxa-1,8-diazaspiro[4.5]dec-1-ene 30 (0.22 g, 0.49 mmol) and palladium hydroxide (0.02 g, 10% wt) in ethanol (10 ml) is placed in a Parr apparatus under a hydrogen atmosphere (40 psi) overnight. After this time, palladium hydroxide (0.02 g, 10% wt) is added again, and the mixture is stirred further under hydrogen at 50° C. for 2 days. The mixture is then filtered on celite and the filtrate is concentrated under reduced pressure to give 0.22 g of 2-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}-3-oxa-1,8-diazaspiro[4.5]dec-1-ene 36 as a paste.
