Sodium hydride → tert-Butyl-4-((6-(5-(3-isopropyl-1,2,4-oxadiazol-5-yl)-1H-indol-1-yl) pyridin-3-yl) oxy)piperidine-1-carboxylate

温度

60 °C

To a stirred solution of N′-hydroxyisobutyrimidamide (0.10 g, 1.0 mmol) in dry THF (10 mL), NaH (0.078 g, 3.26 mmol) was added and stirred at 60° C. for 2 h. The reaction contents were brought to room temperature, Ethyl-1-(5-((1-(tert-butoxycarbonyl)piperidin-4-yl) oxy) pyridin-2-yl)-1H-indole-5-carboxylate (0.205 g, 0.440 mmol) was added and stirred at 60° C. for 3 h. The reaction was quenched by methanol at 0° C. and concentrated in vacuo. The resultant residue was dissolved with ethyl acetate and washed with water, the organic layer was separated, concentrated in vacuo and the resulting residue was purified by flash column chromatography to give the title compound (0.050 g, 10.16%).
