49679-45-0, Ethyl 3-chloroquinoxaline-2-carboxylate is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE 10 2-(Aminoiminomethylthio)-3-quinoxalinecarboxylic acid ethyl ester, hydrochloride 2-Chloro-3-quinoxalinecarboxylic acid ethyl ester (9.5 g., 0.04 mole) and 3.052 g. (0.04 mole) of thiourea were dissolved in 200 ml. of acetone. The solution was boiled in an open flask for 11/2 hours during which acetone was added to maintain the volume at 200 ml. The reaction mixture was cooled and the solid was collected by filtration to give 7.8 g. of crude product. Recrystallization from methanol-acetone afforded 3.55 g. of off-white solid, over wide range dec. Analysis for: C12 H13 ClN4 O2 S Calculated: C, 46.08; H, 4.19; N, 17.91; Cl, 11.33; S, 10.25. Found: C, 46.01; H, 4.13; N, 17.85; Cl, 11.38; S, 10.32. An additional 4.05 g. of product was recovered from the reaction mixture to give a total yield of 7.60 g. (59.3%). Found: C, 46.06; H, 4.14; N, 17.79; Cl, 11.38; S, 10.37
49679-45-0, As the paragraph descriping shows that 49679-45-0 is playing an increasingly important role.
