実験手順

After dissolving N-(2-chloro-4-((6-cyano-7-(4-piperidylmethoxy)-4-quinolyl)oxy)phenyl)-N′-cyclopropylurea (540 mg, 0.846 mmol) in tetrahydrofuran (20 ml)-methanol (20 ml), there were added 37% aqueous formaldehyde (1 ml), acetic acid (0.10 ml, 1.69 mmol) and sodium cyanoborohydride (106 mg, 1.69 mmol) at room temperature, and the mixture was stirred for 1 hour. The reaction solution was distributed between ethyl acetate and saturated aqueous sodium bicarbonate, and the organic layer was washed with saturated saline and dried over anhydrous sodium sulfate. The solvent was distilled off, the residue was suspended in ethyl acetate and diluted with hexane, and the crystals were filtered out and blow-dried to obtain the title compound (282 mg, 0.557 mmol, 65.9%) as white crystals.
