반응 단계
Diethanolamine (11 grams; 0.105 mol), triethylamine (12 grams) and toluene (100 ml) were placed in a 250 ml, 3-necked glass reaction flask equipped with stirrer, thermometer and reflux condenser. 2-methoxy-3,6-dichlorobenzoic acid chloride (23.9 grams; 0.1 mol) in toluene (25 ml) were added to the reaction mixture by means of an addition funnel. The reaction mixture was stirred for two hours and then filtered. The recovered solid material was heated in ethyl acetate and filtered. Toluene was added to the oily residue, heated to dissolve the oil and cooled. The desired product first formed as an oil and then crystalized. The product weighed 23.6 grams representing a yield of 76%.
