Reaction Steps
A solution of NCS (0.36 g, 2.70 mmol) in DMF (2 mL) was treated with acetaldoxime (0.16 g, 2.70 mmol), stirred at RT for 0.5 h, added to a solution of tert-butyl (5-((2-ethynylpyridin-4-yl)oxy)pyridin-2-yl)carbamate (0.28 g, 0.90 mmol) and TEA (2 mL) in DMF (2 mL) and heated at 60° C. for 2 h. The mixture was treated with water, extracted with EtOAc (3×) and the combined organics were washed with brine, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford tert-butyl (5-((2-(3-methylisoxazol-5-yl)pyridin-4-yl)oxy)pyridin-2-yl)carbamate (250 mg, 75%). MS (ESI) m/z: 369.1 (M+H+).
