Participants

Conditions

Temperature: 60 °C

Procedure

After adding tetrahydrofuran (2.0 ml) and piperidine (0.20 ml) to N-(4-{6-cyano-7-[(2R)-oxiran-2-yl]methoxyquinolin-4-yloxy}-2-chlorophenyl)-N′-methylurea (110 mg), the mixture was heated at 60° C. for 3 hours. The reaction solution was purified by NH silica gel column chromatography (ethyl acetate-methanol system) to obtain the title compound (80 mg) as light yellow crystals.
