実験手順
To a stirred mixture of 20 g. (0.0655 mole) of 2,4-dichloro-3,5-dinitrobenzotrifluoride and 150 ml. of absolute ethanol was added 9.58 g. (0.131 mole) of sec-butylamine, dropwise, over a period of about 15 minutes. The resultant solution was refluxed for 2 hours and the ethanol then removed by distillation under reduced pressure. The solid yellow residue was triturated with 300 ml. water to dissolve the sec-butylamine hydrochloride. The water insoluble product was isolated by filtration, washed with water, and then dissolved in 600 ml. of refluxing 95% ethanol. Upon cooling, the product crystallized. Filtration gave 20.4 g. of a yellow crystalline solid, melting at 90.5°-91.5° C.
