Procedure
N-chlorosuccinimide (0.318 g, 2.4 mmol) was added to a stirred solution of methyl 1H-imidazole-4-carboxylate (0.300 g, 2.4 mmol) in CH3CN (16 mL). The reaction mixture was stirred for 12 h in the dark and then concentrated. The white residue was taken up in EtOAc, satd. aqueous Na2S (10 mL) was added and the solution was stirred for 15 min. The organic layer was isolated, dried (Na2SO4), concentrated and the crude product was purified by column chromatography (20-70% EtOAc/hexanes) to afford the title compound (0.061 g, 16%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.05 (br. s., 1H), 7.85 (s, 1H), 3.81 (s, 3H). ES-LCMS: m/z 160.9, 162.9 (M+1).
