Participants

Reaction Steps

To a solution of 3-chlorosulfonylbenzoic acid (3-1) (Maybridge Chemicals) (1.10 g, 5 mmoles) and β-alanine ethyl ester (0.85 g, 5.5 mmoles) in CHCl3 (20 ml) at room temperature was added triethylamine (1.52 g, 15 mmoles). After stirring for 3 hrs the solvent was removed, the residue was taken up in EtOAc, washed with H2O, 10% KHSO4 solution, H2O, brine and dried (Na2SO4). Solvent removal gave a residue that was purified by flash chromatography on silica gel eluting with CHCl3 (97)/MeOH(3) to give pure 3-2.
