Reaction Steps
A mixture of 4-bromo-2-fluorobenzoic acid (2 g, 9.1 mmol), benzyl piperazine-1-carboxylate (2.4 g, 10.9 mmol) and K2CO3 (2.5 g, 18.26 mmol) in DMF (40 mL) was stirred at 150° C. for 36 h. The reaction was then cooled to RT and extracted with ethyl acetate, 3 N HCl, brine, dried over Na2SO4, filtered and concentrated in vacuo to provide 2-(4-((benzyloxy) carbonyl)piperazin-1-yl)-4-bromobenzoic acid as yellow oil that was used without further purification.
