Conditions

Temperature: 60 °C

Procedure

After dissolving N-(4-(6-cyano-7-((2R)-oxiran-2-yl)methoxy-4-quinolyl)oxyphenyl)-N′-(4-fluorophenyl)urea (200 mg, 0.425 mmol) in tetrahydrofuran (5.0 ml) under a nitrogen atmosphere, diethylamine (1.0 ml) was added and the mixture was stirred overnight at 60° C. The reaction solution was concentrated under reduced pressure, the residue was subjected to silica gel column chromatography (eluent—ethyl acetate:methanol=9:1), the fraction containing the target substance was concentrated, methanol (5 ml) was added for crystallization, and the crystals were filtered out and blow-dried to obtain the title compound (126.4 mg, 0.233 mmol, 54.7%) as light yellow crystals.
