Procedure

1-[2-Fluoro-4-(2-{[4-(4-methylpiperazin-1-yl)piperidine-1-carbonyl]amino}piperidin-4-yloxy)phenylcarbamoyl]cyclopropanecarboxylic acid benzyl ester (189 mg) was dissolved in ethyl acetate (6 ml), and 4N hydrochloric acid in ethyl acetate (0.3 ml) was added. The resultant mixture was concentrated under reduced pressure, and methanol (0.5 ml) and ethyl acetate (4 ml) was added. The precipitate obtained by filtration was hygroscopic, thus it was collected using methanol (10 ml). The collected solution was again concentrated under reduced pressure, and methanol (0.5 ml) and tert-butyl methyl ether (4 ml) was added. The precipitate was filtered to give the title compound (102 mg).
