Participants

Reaction Steps

2-[3-[3-(Piperidinomethyl)phenoxy]propylamino]-4-benzyloxypyridine-N-oxide (0.94 g) in ethanol (100 ml) was hydrogenated at 344 KPa (50 p.s.i.), for 5 hours in the presence of 10% palladium on charcoal (0.1 g). The reaction mixture was filtered and the filtrate evaporated under reduced pressure to give an oil. Trituration under diethyl ether containing a little isopropanol gave as a buff solid 2-[3-[3-(piperidinomethyl)phenoxy]propylamino]-4-hydroxypyridine-N-oxide (0.59 g), m.p. 140°-142.5° C. (recrystallised from isopropanol-acetone).
