反応手順

4-Chloro-3,5-dinitrobenzotrifluoride (5.4 grams; 0.02 mole) dissolved in benzene was charged into a glass reaction vessel equipped with a mechanical stirrer and addition funnel. N-Methyl-N-2,2-dimethoxyethylamine (2,4 grams; 0.02 mole) and triethylamine (2.02 grams; 0.02 mole) both dissolved in benzene (50 ml) were then added dropwise with stirring. After the addition was completed stirring was continued for a period of 1 hour resulting in the formation of a precipitate. The reaction mixture was filtered to remove the acid acceptor salt and was chromatographed. The solution was then evaporated to yield a solid product. This solid was recrystallized from hexane to yield the desired product N-methyl-N-(2,2-dimethoxyethyl)-2,6-dinitro-4-trifluoroemethylaniline melting at 48° to 50° C.
