Reaction Steps

A mixture of 5-bromobenzo[d]oxazol-2(3H)-one (2.06 g), 1-bromo-2-methoxyethane (1.085 mL) and potassium carbonate (3.99 g) in acetonitrile (15 mL) was heated at 60° C. for 16 h. Water was added and the mixture was extracted with ethyl acetate (3 times). The organic layers were dried over magnesium sulfate, evaporated and purified by flash silica chromatography eluting with 5:1 isohexane/acetone to give the subtitled compound (1.359 g).
