実験手順

To a solution of 1-(2-cyclopropyl-3-methylimidazo[1,2-a]pyridin-6-yl)-4-hydroxypyridin-2(1H)-one (150 mg), (3-fluorophenyl)-methanol (134 mg) and tributylphosphine (322 mg) in THF (15 ml) was added 1,1′-(azodicarbonyl)dipiperidine (401 mg). The mixture was stirred under sonication at 60° C. for 4 h. The reaction mixture was then cooled to room temperature and concentrated in vacuo. The residue was diluted with DCM (100 ml), and the DCM layer was washed with water and brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM) to give the title compound (45 mg) as a white solid.
