Diisopropylethylamine → 5-(5-Methyl-3-pyridin-2-yl-isoxazol-4-ylmethoxy)-pyridine-2-carboxylic acid (tetrahydro-pyran-4-yl)-amide

Participants

Reaction Steps

To a solution of 5-(5-methyl-3-pyridin-2-yl-isoxazol-4-ylmethoxy)-pyridine-2-carboxylic acid (30 mg, 0.1 mmol) in DMF (1 mL) were added 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (34 mg, 0.1 mmol), N,N-diisopropyl ethyl amine (83 μL, 0.48 mmol) and 4-aminotetrahydropyran (11 mg, 0.1 mmol). The resulting reaction mixture was stirred overnight at room temperature. The reaction mixture was evaporated and purification by chromatography (silica, heptane:ethyl acetate=100:0 to 2:3) afforded the title compound (29 mg, 76%) as a white solid. MS: m/e=395.2 [M+H]+.
