Triethylamine → HCID 86692087, compound

Participants

Reaction Steps

0.75 g of 4-chloro-6-iodoquinazoline, 0.51 g of 2,3,4a,8a-tetrahydro-1H-quinolin-4-one and 0.96 ml of triethylamine in 5 ml of dioxane are heated at 80° C. in a flask until the quinazoline has reacted completely (HPLC check, about 24 hours). The cooled reaction solution is diluted with EA and washed 3 times with water. The organic phase is dried over sodium sulfate and purified by means of column chromatography (gradient heptane: EA 5-100% in 16 min.), giving 0.40 g of 1-(6-iodoquinazolin-4-yl)-2,3,4a,8a-tetrahydro-1H-quinolin-4-one as yellowish solid (yield 40%, content 91%); MS-FAB (M+H+)=402.0; Rf (polar method): 2.20 min.
