Three dimethoxy[1]benzothieno[2,3-c]quinolines 24–26 were prepared by photocyclization of the appropriate 3-chloro-N-phenylbenzo[b]thiophene-2-carboxamides 15–17 to [1]benzothieno[2,3-c]quinolin-6(5H)-ones 18–20 followed by chlorination to 6-chloro[1]benzothieno[2,3-c]quinolines 21–23 and then dechlorination resulting in the title compounds. Reaction of 24–26 with methyl iodide furnished the corresponding
通过将合适的3-氯-N-苯基苯并[ b ]噻吩-2-甲酰胺15-17光环化为[1]苯并噻吩并[2,] ,制备了三个二甲氧基[1]苯并噻吩并[2,3- c ]喹啉24-26。 3- ç ]喹啉6(5 ħ) -酮18-20,接着氯化,以6-氯[1]苯并噻吩并[2,3- c ^〕喹啉21-23,然后,获得标题化合物脱氯。的反应24-26用甲基碘提供的相应Ñ -甲基季盐27-29。甲醇钠易于转化21-23到三甲氧基[1]苯并噻吩并[2,3- c ]喹啉30-32。
