Reaction Steps

tert-Butyl (1-(4-aminophenyl)piperidin-4-yl)carbamate (G39) can be prepared by nucleophilic aromatic substitution of commercially available tert-butyl piperidin-4-ylcarbamate (G36) and 1-fluoro-4-nitrobenzene (G37) under thermal conditions to give tert-butyl (1-(4-nitrophenyl)piperidin-4-yl)carbamate (G38). Reduction of G38 with hydrogen in the presence of a catalyst, for example 10% palladium on charcoal gives tert-butyl (1-(4-aminophenyl)piperidin-4-yl)carbamate (G39).
