Procedure

To a suspension of methyl 3-[2-chloro-4-(thiophen-2-yl)benzyl]-2-methyl-3H-imidazo[4,5-b]pyridine-5-carboxylate (50 mg, 0.126 mmol) in acetic acid (1 ml) was added N-chlorosuccinimide (19 mg, 0.138 mmol) at room temperature. Thirty minutes later, dichloromethane (0.5 ml) was added to the reaction mixture to give a clear transparent solution. Four hours later, N-chlorosuccinimide (19 mg, 0.138 mmol) was further added. The reaction mixture was left standing overnight and concentrated. The residue was purified by p-TLC (chloroform/methanol=40/1) to give the object compound (52 mg, 95.7%) as a colorless oil.
