실험 절차

To a solution of 6-(3-methyl-5-pyridin-2-yl-3H-[1,2,3]triazol-4-ylmethoxy)-pyridazine-3-carboxylic acid (98 mg, 0.31 mmol) and TBTU (111 mg, 0.35 mmol) in DMF (2 mL) was added DIPEA (270 μL, 1.57 mmol). Then 4-aminotetrahydropyran (35 mg, 0.35 mmol) was added and the mixture was stirred at room temperature under Ar for 16 h. The mixture was then evaporated and purification by chromatography (silica, 50 to 100% ethyl acetate in heptane) afforded the title compound (101 mg, 81%) as an off white solid. MS: m/e=396.2 [M+H]+.
