Procedure
A solution of tert-butyl 8-(diethylamino)-2,3-dihydro-1,4-benzoxazepine-4(5H)-carboxylate (250 mg, 0.780 mmol) in 4N hydrogen chloride-ethyl acetate (6 ml) was stirred for 1 hr at room temperature, and the solvent was evaporated under reduced pressure. The residue was recrystallized from a mixed solvent of methanol and ether to give the desired product (144 mg, 62.9%) as a solid.
