実験手順
tert-Butyl (2S)-8-(3-fluorophenyl)-2-methyl-2,3-dihydrothieno[2,3-f][1,4]oxazepine-4(5H)-carboxylate (416 mg) was stirred in 4N hydrogen chloride-ethyl acetate solution (5 mL) for 20 min. The reaction solution was concentrated under reduced pressure, and the residue was recrystallized from ethyl acetate to give (2S)-8-(3-fluorophenyl)-2-methyl-2,3,4,5-tetrahydrothieno[2,3-f][1,4]oxazepine 1 hydrochloride (315 mg, 92%) as colorless crystals.
