Procedure

A solution of 9.1 g. (0.031 mole) of trans-4-(2,3-dimethylphenoxy)-1-phenylmethyl-3-pyrrolidinol in 100 liters of ethanol was hydrogenated over 10% palladium-on-charcoal at 50 psi and 60° C. until hydrogen uptake ceased. The mixture was filtered through Celite and the filtrate was concentrated to give an oil as residue which solidified upon standing. The solid was converted to the hydrobromide and this salt was recrystallized from isopropyl alcohol-ethylacetate-diethylether to yield 4.9 g (55%) of tan needles, m.p. 152°-3° C.
