It is derived from o-phenylenediamine and formic acid by cyclization. The mixture of o-phenylenediamine and formic acid was heated on a water bath for 2 hours, cooled, and adjusted to pH 10 with 10% sodium hydroxide solution. The precipitated solid was filtered out of Chemicalbook and washed with cold water to obtain a crude product. The crude product is slightly boiled with water, decolorized with activated carbon, filtered while hot, the filtrate is cooled to room temperature, filtered, washed with cold water, and dried at 100°C to obtain the finished product. The yield of crude product is 90%.
