Procedure

4-chloro-3-nitroaniline, 10.1 g (0.058 mole), is dissolved in 100 ml dichloroethane, containing 25 ml pyridine. The solution is stirred at room temperature while nonanoylchloride, 10.5 g (0.067 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. The product does not crystallize from dichloroethane which was removed. The product was crystallized from 80% ethanol. There is obtained N-(4-Chloro-3-nitrophenyl) nonanamide (M.P. 44.5-45.0). Analysis shows 8.9% nitrogen and 11.26% chlorine as against calculated values of 8.96% and 11.33% respectively for C15H21ClN2O3.
