Participants

Reaction Steps

To a mixture of tert-butyl piperazine-1-carboxylate (1.81 g, 9.7 mmol), 3-fluoro-4-methylbenzoic acid (1.50 g, 9.7 mmol), and triethylamine (6.8 mL, 49 mmol) in acetnitrile (30 mL), HBTU (4.06 g, 10.7 mmol) was added. After stirring at rt for 1 h, the mixture was poured onto water (150 mL), and the mixture was extracted with EtOAc (twice). The combined organic layers were dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with hexane/EtOAc (4:1-2:1) to give 3.14 g (quant) of the title compound as a white solid.
