• 2-Chloro-3-methylquinoxaline reacts with aromatic amines in basic medium forming 2-arylamino-3-methylquinoxalines, also it reacts with mercaptoacetic acid. The 3-methyl-2(1<I>H</I>)-quinoxalinone condenses with aromatic aldehydes forming the corresponding 3-(substituted styryl)-2(1<I>H</I>)-quinoxalinones which add bromine in acetic acid to yield the corresponding dibromo derivatives which react with morpholine, sodium methoxide, and piperidine to give the corresponding compounds. 3-Methyl-2(1<I>H</I>)-quinoxalinone undergoes side-chain bromination to yield 3-bromomethyl-2(1<I>H</I>)-quinoxalinone, which reacts with aromatic amines, sodium salt of saccharine, potassium phthalimide··· 3-Methyl-2(1<I>H</I>)-quinoxalinone with P<SUB>2</SUB>S<SUB>5</SUB> gave 3-methyl-2(1<I>H</I>)-quinoxalinethione which reacts with 2-aminoethanol, dimethyl sulfate, and halo acids.
