Participants

Conditions

Temperature: 50 °C

Procedure

After adding tetrahydrofuran (1.5 ml) and piperidine (0.08 ml) to N-[4-(6-cyano-7-oxiranylmethoxyquinolin-4-yloxy)-2-fluorophenyl]-N′-(4-fluorophenyl)urea (78 mg), the mixture was heated at 50° C. for 30 minutes. The reaction solution was purified by NH silica gel column chromatography (ethyl acetate-methanol system) to obtain the title compound (32 mg) as light yellow crystals.
