Abstract
The reaction of quinolin-8-ol with 1,2-dibromoethane in dimethylformamide gave 2,3-dihydro[1,4]-oxazino[2,3,4-ij]quinolinium bromide which reacted with aqueous sodium hydroxide to afford 2,3,4,5-tetrahydro[1,4]oxazino[2,3,4-ij]quinoline, 2,3,4,5-tetrahydro[1,4]oxazino[2,3,4-ij]quinolin-5-ol, and 2,3,4,5-tetrahydro[1,4]oxazino[2,3,4-ij]quinolin-5-one.
