実験手順

Valeryl chloride (12.06 g., 0.10 mole) is added dropwise to a cooled stirred solution of 2-chloro-4-nitroaniline (17.26 g., 0.10 mole) in pyridine (100 ml.). The mixture is warmed to ambient temperature, then heated (80°-100° C.) for twenty-four hours. The cooled solution is poured into cold 1 N hydrochloric acid (500 ml.) with stirring. The precipitated solid is collected, washed well with water and dried, 25.1 g., m.p. 80°-95° C. Recrystallization from cyclohexane yeilds material (19.75 g.) of m.p. 95°-97° C.
