Reaction Steps

4-Amino-2,3,5-trimethylphenol (100 g, 662 mmol) was dissolved in formic acid (500 ml). The mixture was heated under reflux for 36 hours. The reaction mixture was poured into ice-cold water. The precipitated crystals were filtered, washed with water and dried. The crude crystals obtained were recrystallized from ethanol to obtain the desired compound (85.9 g, yield: 72.5%), m.p. 219°-220° C.
