실험 절차

3-[6-(2-Fluoro-4-nitrophenoxy)pyrimidin-4-yl]-1-(3-diethylaminopropyl)-1-methylurea (54.0 mg) was dissolved in tetrahydrofuran (2 ml)-methanol (2 ml), and then 10% palladium carbon (27.2 mg) was added thereto, followed by replacing with hydrogen inside the system and stirring overnight. After replacing with nitrogen inside the system, the reaction mixture was filtered to remove the catalyst, which was washed with methanol. The filtrate was concentrated under a reduced pressure to give a residue, which was then purified by silica gel column chromatography (Fuji Silysia NH, eluent; hexane:ethyl acetate=1:1, then ethyl acetate). Fractions containing the target compound were concentrated under a reduced pressure to provide the titled compound (34.3 mg, 68.6%) as a pale yellow solid.
