Procedure

A mixture of tert-butyl 9-cyclopentyl-2,3-dihydro-1,4-benzoxazepine-4(5H)-carboxylate (130 mg, 0.410 mmol), ethyl acetate (1 ml) and 4N hydrogen chloride-ethyl acetate solution (4 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 (81.3 mg, 78.2%) as a solid.
