To wet 10% palladium on carbon (Degussa catalyst) under nitrogen was added ethanol (100 ml). A solution of 1-Benzhydryl-3-cyclopropyl-3-fluoroazetidine hydrochloride (6.74 g, 21.23 mmol) in ethanol (50 ml) was added to the catalyst and the mixture hydrogenated at 60 psi on the Parr shaker hydrogenation apparatus for 5 hrs. The reaction was filtered through celite and concentrated to an oil. Ether (50 ml) was added and the mixture cooled to 0° C. and stirred until a precipitate formed. The suspension was filtered and the filter cake washed with ether (20 ml) and the solid dried under vacuum. This furnished the product as an off white solid (3.00 g, 93%). 1H NMR d6-DMSO δ 0.52-0.56 (2H, m), 0.59-0.64 (2H, m), 1.35-1.40 (1H, m), 3.91-4.10 (4H, m), 4.01-4.23 (4H, m), 9.50 (1H, brs), 9.63 (1H, brs).
