Sodium hydride → 4-[1-(2-Fluoroethylcarbamoyl)1H-indol-5-yloxy]-6,7-dimethoxyquinoline

Participants

Reaction Steps

4-(1H-Indol-5-yloxy)-6,7-dimethoxyquinoline (75 mg, 0.3122 mmol), sodiumhydride (13 mg, 0.3278 mmol) and phenyl N-(2-fluoroethyl)carbamate (45 mg, 0.3278 mmol) were used for reaction in the same manner as Example 310, followed by extraction with ethyl acetate/tetrahydrofuran, washing with saturated brine and drying over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was adsorbed onto silica gel and subjected to silica gel column chromatography (hexane/ethyl acetate system) to obtain the title compound (24 mg, 0.0586 mmol, 18.78%) as colorless crystals.
