PROCEDURE

实验过程

To a suspension of 2-chloro-4-{2,5-dichloro-4-[3-(4-cyclopropyl-3,4-dihydro-2H-quinoxaline-1-carbonyl)-pyridin-2-yloxy]-phenylethynyl}-benzoic acid (100 mg, 0.16 mmol, 1.0 equiv; Example 168) in ethanol (1.5 mL) was added palladium on carbon (3.2 mg, 0.003 mmol, 0.02 equiv; 10% Pd/C; [CAS RN 7440-05-3]) and the reaction mixture stirred under an atmosphere of hydrogen (3 bar) at rt over night. Removal of the solvent mixture under reduced pressure, filtration over Celite® and lyophilization from dioxane provided 100 mg (96%) of the title compound as an off-white solid. MS (ISP): 620.3 [M−H]−.
