Wk. Anderson et Dk. Dalvie, SYNTHESIS OF LOROETHYL)-2,3-DIHYDRO[1,4]OXAZINO[2,3-B]QUINOLINE AND -CHLOROETHYL)-2,3-DIHYDROPYRIDO[2,3-B][1,4]OXAZINE, Journal of heterocyclic chemistry, 30(6), 1993, pp. 1533-1536
The title compounds were synthesized from 3-[bis(2-hydroxyethyl)amino]
quinolin-2(1H)-one 11a and 3-[bis(2-hydroxyethyl)amino]pyridin-2(1H)-o
ne 18 respectively. The preparation involved a tandem chlorination/cyc
lization reaction.
