Procedure

A solution of methyl 2-methylnicotinate (20.0 g, 0.132 mol) and trichloroisocyanuric acid (46.0 g, 0.198 mol) in dichloromethane (100 mL) was stirred at room temperature overnight. The reaction mixture was then washed with saturated aqueous sodium carbonate and saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, filtered, and the solvent evaporated in vacuo to provide the title compound as a yellow liquid (11.2 g), which is used as such in the next step.
