Participants

Reaction Steps

A mixture of intermediate (49) (0.065 mol) in THF (250 ml) was treated with liquid NH3 in an autoclave at 125° C. during 16 hours. The reaction mixture was filtered and the filtrate was evaporated. The residue was partitioned between a 5% aqueous NaOH solution and DCM. The organic layer was separated, dried, filtered and the solvent was evaporated, yielding 16 g of 1,1-dimethylethyl(trans)-4-(aminomethyl)-3-methoxy-1-piperidinecarboxylate (intermediate (50).
