Pyridine → N-(4-Nitrophenyl)nonanamide

Participants

Reaction Steps

p-Nitroaniline, 13.0 g (0.094 mole), is dissolved in 200 ml dichloroethane, containing 25 ml pyridine. The solution is stirred at 50° C. while nonanoylchloride, 16.5 g (0.094 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 then passed through a florisil column and crystallized at -20° C. There is obtained N-(4-nitrophenyl) nonanamide, (M.P. 76.0°-76.5°). Analysis shows 9.91% nitrogen as against a calculated value of 10.06% for C15H21N2O3.
