実験手順

A mixed solution of tert-butyl (2S)-8-bromo-2-methyl-2,3-dihydrothieno[2,3-f][1,4]oxazepine-4(5H)-carboxylate (599 mg) obtained in Example 12, steps 1-4, cis-propenylboronic acid (192 mg), dichlorobis(triphenylphosphine)palladium (60 mg) and potassium carbonate (713 mg) in DME-water (1:1, 20 mL) was stirred at 85° C. for 4 hr under a nitrogen stream. The reaction solution was cooled to room temperature, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (solvent gradient; 5→15% ethyl acetate/hexane) to give the title compound (399 mg, 75%) as a colorless oil.
