A mixture of 3-chloro-6-(methylsulfonyl)-2,4-dinitrotoluene (10.0 g., 0.034 mole) and 2-aminopentane (6.1 g. 0.07 mole) is refluxed in benzene (75 ml.) for 4 hours. After standing overnight, the mixture is successively washed with dilute hydrochloric acid, water, a 5% aqueous potassium carbonate solution and finally water. The mixture is then dried over magnesium sulfate. Removal of the magnesium sulfate and solvent leaves the desired product as a yellow oil which readily crystallized on cooling. The crude product is recrystallized from ethanol to give 9.5 grams with m.p. 85°-88° C.
