Participants

Reaction Steps

A suspension of 92 g of 1-benzyl 4-trifluoromethylcarbonylamino piperidine (X) and 9 g of wet 10% palladium on charcoal in 1000 ml of methanol is left under agitation for 8 days in a hydrogen atmosphere at room temperature. Then it is filtered, the filtrate is evaporated and the residue chromatographed on a silica column (M.P.L.C.). By eluting with pure methanol, 44 g of the expected product are obtained.
