Reaction Steps

1-Boc-piperazine and 4-nitrobenzoyl chloride were allowed to undergo the reaction in DMF in the presence of triethylamine, and then the nitro group was reduced in the sama manner as the catalytic hydrogenation shown in Reference Example 3 to obtain tert-butyl 4-(4-aminobenzoyl)piperazine-1-carboxylate. ESI: 307.
