Procedure
After dissolving 4-(4-amino-3-chlorophenoxy)-6-cyano-7-((2R)-oxiran-2-yl)methoxyquinoline (96 mg, 0.261 mmol) in tetrahydrofuran (2.6 ml) under a nitrogen atmosphere, diethylamine (0.5 ml) was added and the mixture was stirred at 50° C. for 5 days. The reaction solution was concentrated under reduced pressure, the residue was subjected to silica gel column chromatography (eluent-ethyl acetate), the fraction containing the target substance was concentrated, suspended in ethyl acetate and diluted with hexane, and the crystals were filtered out and blow-dried to obtain the title compound (96.9 mg, 0.220 mmol, 84.2%) as light yellow crystals.
