19.1g (0.1 mole) of 4-acetamino-3-methyl-N-ethylaniline obtained in Example 1, Part C, and 100g of water were mixed, and, after 12.5g of diethyl sulfate were added dropwise thereto while stirring, the entire reaction system was stirred overnight at room temperature. Next, the reaction mixture was neutralized with sodium hydroxide and the crystals separated were recrystallized from methanol to obtain 11.5g of white crystals of 4-acetamino-3-methyl-(N,N-diethyl)aniline.
