반응 단계
A mixture of 5-bromobenzo[d]oxazol-2(3H)-one (1.1 g), 3-methoxypropyl methanesulfonate (1.297 g) and potassium carbonate (2.131 g) in acetonitrile (25 mL) was heated at 70° C. for 16 h. Water was added and the mixture was extracted with ethyl acetate (3 times). The organic layers were dried (MgSO4), evaporated and purified by flash chromatography (silica, isohexane-acetone (5:1) as eluent) to give the sub-titled compound (1.50 g) as an oil.
