Procedure
2-Bromo-1-(3-nitrophenyl)ethanone (1.01 g, 4.14 mmol) was dissolved in THF (20 mL) and added (S)-tert-butyl 3-(hydroxymethyl)piperazine-1-carboxylate (1.074 g, 4.97 mmol) followed by Hunig's base (1.45 mL, 8.28 mmol) then stirred at room temperature overnight. The reaction was poured into water and extracted with ETOAC (2×). The organic layer was separated, dried over Na2SO4, filtered and concentrated. The product was purified by chromatography through a 120 g ISCO Redi-sep column eluting with 0-70% ethyl acetate/hexane to yield the title compound.
