実験手順

A 83 ml portion of ethanol was added to a mixture of 4.14 g of trimethylpyruvic acid synthesized in accordance with the method of Jaeger et al. (J. Am. Chem. Soc., pp.717-732, 1979) and 3.02 g of o-phenylenediamine. The thus prepared mixture was refluxed for 3 hours in an atmosphere of nitrogen. By concentrating the resulting reaction solution, 3.15 g of 2-t-butyl-3, 4-dihydro-3-oxoquinoxaline was obtained.
