EXAMPLE 16 2-[(Butylamino)(butylimino)methylthio]-3-quinoxalinecarboxylic acid ethyl ester, hydrochloride 2-Chloro-3-quinoxalinecarboxylic acid ethyl ester (7.10 g., 0.03 mole) was dissolved in 125 ml. of acetone treated with Norit and filtered. The filtrate was added to 5.650 g. (0.03 mole) of 1,3-di-n-butylthiourea in 100 ml. of acetone. The solution was stirred at reflux under a nitrogen atmosphere for 6 hours, allowed to cool to room temperature, and stirred an additional 17 hours. The red solution was treated with Norit, filtered, and concentrated to a volume of 100 ml. The yellow solid that crystallized out was collected by filtration, washed and dried to give the 6.05 g. (47.5% yield) of product, m.p. 138-139 C. (dec.). Analysis for: C20 H29 ClN4 O2 S Calculated: C, 56.52; H, 6.88; N, 13.18; Cl, 8.34. Found: C, 56.74; H, 6.78; N, 13.25; Cl, 8.09.
49679-45-0, The synthetic route of 49679-45-0 has been constantly updated, and we look forward to future research findings.
