2-Chloro-3-methylquinoxaline (10.72 g., 0.06 mole) was dissolved in 150 ml. of acetone, treated with Norit and filtered. The filtrate was added to 4.56 g. (0.06 mole) of thiourea in 150 ml. acetone. The solution was stirred at reflux under nitrogen for 2 hours. The precipitate which began to form after 5 minutes, was filtered while the reaction mixture was hot.
