2-(Trifluoromethyl)benzoyl chloride → HCID 44203150, compound

Participants

Reaction Steps

4.57 g 3-amino-2-chloropyridine (36 mmol) and 30 mL pyridine were mixed in an ice bath. 8.24 g 2-trifluoromethyl benzoyl chloride (40 mol) was then added. After return to room temperature and reaction for 4 hr, the reaction was quenched by water. After extraction three times by ethyl acetate, an ethyl acetate layer was collected and washed by 1M HCl solution. After drying, filtration, concentration, and purification by silicon-gel column, 9.9 g solid was obtained, with a yield of 92%.
