Yield	Reaction Conditions	Operation in experiment
	With N-chloro-succinimide; In N,N-dimethyl-formamide; at 40℃; for 4.0h;	To a solution of <strong>[860457-99-4]ethyl 6-(trifluoromethyl)imidazo[1,2-a]pyridine-2-carboxylate</strong> (Intermediate I-4 prepared as described above) (8.5 g, 33 mmol) in N,N-dimethylformamide (85 mL) was added 1- chloropyrrolidine-2,5-dione (5.3 g, 40 mmol) at room temperature. The reaction mass was heated at 40 15 C for 4 hours. After completion, the reaction mass was quenched with ice cold water, solid was precipitated and the obtained solid was filtered through a Buchner funnel, dried in vacuo to afford ethyl 3-chloro-6-(trifluoromethyl)imidazo[1,2-a]pyridine-2-carboxylate as a solid. LCMS (Method 2): Rt= 1.45 min, m/z=293 (M+H)+.
