Methanol (128 g) was added to 344 g (4 moles) of methyl acrylate containing 500 ppm of methoxyhydroquinone and, while stirring and placed in a water bath, 404 g (4 moles) of dipropylamine was added dropwise thereinto over a period of 30 minutes. After completion of the dropping, the reaction was continued at 70° C. for three hours. After completion of the reaction, methanol was evaporated therefrom to give 746 g of methyl beta-dipropylaminopropionate. The purity as checked by gas chromatography was 99%.
