Reaction Steps

To a cooled suspension of 54.0 g. (1 mole) of sodium methoxide in a liter of dry ether, a mixture of 80 ml. (1.3 moles) of methylformate and 76 ml. (1 mole) of y-butyrolactone was added dropwise with stirring over a 2-h period. The stirring was continued at room temperature overnight. The reaction mixture was then cooled in an ice bath for 1 hr. to complete the separation of the cream-colored product which was then collected, washed with dry ether, and dried under vacuum to yield sodium (Z)-(2-oxodihydrofuran-3(2H)-ylidene)methanolate (123 g, 90%)
