Reaction Conditions

Reaction Steps

After adding (2R)oxiran-2-ylmethyl 4-methyl-1-benzenesulfonate (308 mg, 1.35 mmol), potassium carbonate (149 mg, 1.08 mmol) and dimethylformamide (9 ml) to 4-(3-chloro-4-(((cyclopropylamino)carbonyl)amino)phenoxy)-7-hydroxy-6-quinolinecarboxamide (372.0 mg, 0.90 mmol), the mixture was stirred at 60° C. for 6 hours. Next, diethylamine (2 ml) was added and the mixture was further stirred overnight at 50° C. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with water and saturated saline and then dried over anhydrous sodium sulfate. The solvent was distilled off, the residue was subjected to silica gel column chromatography (eluent-ethyl acetate:methanol=95:5), the fraction containing the target substance was concentrated, and crystals were precipitated from diethyl ether, filtered out and blow-dried to obtain the title compound (177.5 mg, 0.327 mmol, 36.3%) as white crystals.
