Reaction Steps

Into a 250-mL round bottom flask, was placed 4-bromo-7-hydroxy-2,3-dihydro-1H-inden-1-one (1.5 g, 6.61 mmol, 1.00 equiv), CH3CN (30 mL) and potassium carbonate (1.83 g, 13.24 mmol, 2.00 equiv). BnBr (1.18 g, 6.90 mmol, 1.04 equiv) was added dropwise. The resulting solution was stirred for 2 h at 60° C. in an oil bath. The reaction progress was monitored by TLC (ethyl acetate/petroleum ether=1:4). The solids were removed by filtration. The resulting mixture was concentrated under reduced pressure. The residue was applied to a silica gel column, eluting with ethyl acetate/petroleum ether (1:4). This resulted in 2.1 g (95%) of 7-(benzyloxy)-4-bromo-2,3-dihydro-1H-inden-1-one as a yellow solid.
