실험 절차

3,5-Dinitroaniline, 10.0 g (0.055 mole), is dissolved in 200 ml dichloroethane, containing 25 ml pyridine. The solution is stirred at room temperature while nonanoyl chloride, 10.3 g (0.058 mole), is added slowly. The solution is stirred for 2 hours. Excess pyridine is removed by washing the product with 4N hydrochloric acid. The product is obtained by crystallization at -20° C. and recrystallized from 95% ethanol. There is obtained N-(3,5-Dinitrophenyl) nonanamide (M.P. 72.5°-73.0° C.). Analysis shows 12.69% nitrogen as against a calculated value of 12.61% for C15H21N3O5.
