Procedure

To a stirred solution of 30 parts of (3,4-diaminophenyl) phenylmethanone in 240 parts of methanol were added 30 parts of an ethanedial solution in water 40%. The reaction mixture was stirred for 3 hours at reflux temperature. After cooling to room temperature, the precipitated product was filtered off, washed with methanol and dried, yielding 20 parts (59.3%) of phenyl (6-quinoxalinyl)methanone; mp. 120° C. (interm. 2).
