2-methyl resorcinol (0.161 mmol, 20.024 g) and malic acid (0.165 mmol, 22.129 g) were dissolved in concentrated sulfuric acid. The reaction mixture was stirred at 80° C. for 24h. The resulting solution was then poured over crushed ice, and the precipitate was collected by vacuum filtration. The precipitate was then washed with 5% NaHCO3 and again collected by vacuum filtration yielding an orange-yellow solid in a 20.64% yield.
