Procedure

2-Chloro-3-methylquinoxaline (3.56 g., 0.02 mole) was dissolved in 50 ml. of methanol, treated with Norit and filtered. The filtrate was added to 3.125 g. (0.02 mole) of 1,3-diallylthiourea in 50 ml. of methanol. The mixture was stirred at room temperature for 31/2 hours, then freed of solvent. Acetone was added to the residue and the solution again freed of solvent. The residue was triturated with ether and with acetone, filtered, washed and dried to give 4.12 g. (61.5% yield), m.p. 90°-93° C.
