実験手順

To 2-(4,5-dibromo-6-oxopyridazin-1(6H)-yl)-N-(pyridin-4-ylmethyl)acetamide (50 mg, 0.124 mmol) and (1R,2R,3R,5S)-(−)-isopinocampheol (50 mg, 0.324 mmol) in 1,4-dioxane (2 mL), sodium hydride (15 mg, 0.313 mmol) was added at 0° C., and stirred at 100° C. for 5 days. After completion of the reaction, the reaction mixture was mixed with water and extracted with chloroform and ethyl acetate. The combined organic layer was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate) to give the desired product (1.7 mg, 3% yield).
