EXAMPLE 15 2-[(Propylamino)(propylimino)methylthio]-3-quinoxalinecarboxylic acid ethyl ester, hydrochloride 2-Chloro-3-quinoxalinecarboxylic acid ethyl ester (3.551 g., 0.015 mole) and 2.405 g. (0.015 mole) of 1,3-di-n-propylthiourea were dissolved in acetone and heated at reflux for 11/2 hours. The solution was concentrated to a volume of 50 ml. and cooled. A small amount of solid was removed by filtration. The filtrate was further concentrated to a volume of 25 ml. and ether was added to turbidity. After the reaction mixture had been cooled the yellow solid was collected by filtration to give 2.77 g. (46.6%) of the product, m.p. 129-130 C. Analysis for: C18 H25 ClN4 O2 S Calculated: C, 54.47; H, 6.35; N, 14.12; Cl, 8.93; S, 8.08. Found: C, 54.42; H, 6.50; N, 14.12; Cl, 8.87; S, 8.07., 49679-45-0
