Reaction Conditions

Reaction Steps

A one-liter flask was purged with nitrogen while dry 2,6-dichlorobenzamide (125 grams, 0.64 mole) and dry toluene (300 ml.) were added. The nitrogen purge was continued as oxalyl chloride (100 grams, 0.79 mole) was added over a 15-minute period, with stirring. The reaction mixture was then heated to 55° C. and stirred overnight (about 18 hours) at 55° C.
