Reaction Steps

[step 2] (E)-2-{8-[(2-methyl-7-trimethylsilylethynylimidazo[1,2-a]pyridin-3-yl)methyl]-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene}propanenitrile (340 mg, 0.62 mmol) obtained in step 1 was dissolved in THF (3 ml), 1 mmol/L tetrabutylammonium fluoride THF solution (0.81 ml, 0.81 mmol) was added, and the mixture was stirred at room temperature for 4 hr. Water was added to the reaction mixture and the mixture was extracted 3 times with ethyl acetate. The combined organic layers were dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (heptane/ethyl acetate=1/2 v/v) to give the title compound (152 mg, 53%).
