Reaction Steps

To a solution of 37.1 g of N-formylpiperazine and 37.1 g of anhydrous sodium carbonate in 50 mL of methanol was added dropwise 53.15 g of methoxyethyl bromide, and the mixture was refluxed for 3.5 hours. After cooling to room temperature, insolubles were filtered out and the filtrate was concentrated. To the residue was added water and chloroform. After separating the organic layer, the aqueous layer was extracted with chloroform. The combined organic layer was dried over anhydrous magnesium sulfate and concentrated to give 57.2 g of the title compound.
