Reaction Steps

[step 6] (E)-2-{8-[(8-chloro-2-cyclopropylimidazo[1,2-a]pyrazin-3-yl)methyl]-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene}propanenitrile (0.2 g, 0.43 mmol) obtained in step 5 was dissolved in THF (1.4 mL), and 2 mol/L dimethylamine THF solution (1.7 mL, 3.4 mmol) was added. The mixture was stirred with heating at 100° C. for 1.5 hr in an Emrys Optimizer microwave synthesizer. Water was added to the 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 residue was purified by silica gel column chromatography (heptane/ethyl acetate=100/0 v/v-50/50 v/v) to give the title compound (0.18 g, 87%).
