実験手順
To 25 ml of 2,6-xylidine (0.20 mole) was added slowly a mixture of 25 ml of acetic anhydride (0.26 mole) and 25 ml of acetic acid (0.44 mole) under stirring at room temperature. The mixture was stirred for 30 minutes at room temperature and, then, diluted with water. The crystalline precipitate was collected by filtration to give 30.1 g (91%) of the title compound (m.p. 182°-184° C.; colorless needles).
