Reaction Steps

A solution of 7-hydroxy-6-methoxybenzofuran-3(2H)-one (0.30 g, 1.7 mmol) in DMF (5.0 mL) was added with potassium carbonate (1.0 g, 7.2 mmol), and N-Boc-4-bromopiperidine (0.50 g, 1.9 mmol), and the mixture was stirred at 80° C. for 12 hours. The reaction mixture was added with ethyl acetate, and then the organic layer was washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was subjected to silica gel column chromatography (eluted with hexane/ethyl acetate (1:1)) to obtain tert-butyl 4-(6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yloxy)piperidine-1-carboxylate (0.019 g, 3%).
