Reaction Steps

To a solution of N-(2-oxobutyl)-4-methoxybenzo(b)furan-2-carboxamide (2.00 g) in THF (60 ml) was added Burgess reagent (7.30 g), and the mixture was stirred with refluxing. Water (200 ml) was added to the reaction mixture and the mixture was extracted with ether. The organic layer was washed with water and saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound (1.56 g) as colorless crystals, melting point 88–87° C.
