Synthesis of 2-bromomethyl-4-methyl-2,3-dihydrofuro[3,2-c]-quinoline and some its transformations

Electrophilic intramolecular heterocyclization of 3-(2-chloroprop-2-en-1-yl)-2-methylquinolin-4-ol by the action of bromine gave 2-bromomethyl-2-chloro-4-methyl-2,3-dihydrofuro[3,2-c]quinoline hydrobromide which was converted into 2-hydroxymethyl-, 2-alkoxymethyl-, and 2-dialkylaminomethyl-4-methylfuro[3,2-c]quinolines by treatment with the corresponding nucleophiles.
