Reaction Steps

3-[4-(4-Nitrophenoxy)pyridin-2-yl]-1,1-dimethylurea (607 mg) was dissolved in tetrahydrofuran (20 ml)-methanol (20 ml), and then 10% palladium carbon (236 mg) was added thereto under a nitrogen atmosphere, 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 dried in vacuum to provide the titled compound (529.5 mg, 96.7%).
