실험 절차

Acetic anhydride (0.18 ml) was added dropwise to a solution of 3-(7-fluoro-2,3-dihydro-benzofuran-4-yl)-propylamine (256 mg) in, dry THF (10 ml) containing pyridine (0.21 ml) at 0° under nitrogen and the solution stirred overnight at room temperature. The solution was evaporated and the residue purified by column chromatography. Eluting with dichloromethane:methanol: (50:1) gave the title compound as a colouriess oil (133 mg)
