Reaction Steps

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.522 g, 1.50 mmol), benzyl alcohol (0.186 mL, 1.80 mmol) and triphenylphosphine (0.590 g, 2.25 mmol) in toluene (6 mL) was added with a 40% solution of diethyl azodicarboxylate in toluene (0.980 g, 2.25 mmol), and the mixture was stirred at 110° C. for 5 hours in a sealed tube. The reaction mixture was concentrated, and the resulting residue was subjected to silica gel column chromatography (chloroform/ethyl acetate) to obtain tert-butyl 4-{[6-(benzyloxy)-3-oxo-2,3-dihydrobenzofuran-7-yl]methyl}piperazine-1-carboxylate (0.259 g, 39%).
