86% 6 2-Dimethylaminomethylacrylic acid. EXAMPLE 6 2-Dimethylaminomethylacrylic acid. Aqueous formaldehyde (162 ml of 37% solution) was slowly added to a solution of malonic acid (104g) and dimethylamine (350 ml 26% of aqueous solution) in water (150 ml) at 15° C with stirring. Carbon dioxide was evolved at a rate dependent upon the rate of addition of formaldehyde. The reaction mixture was stirred for 30 minutes at 15° C and then heated on a steam bath for 1 hour to ensure complete decarboxylation. Evaporation of the solvent under reduced pressure gave a yellow syrup, which was dried further by azeotropic distillation with toluene to obtain a pale brown solid. The crude material was recrystallized from acetone and dried in vacuum over phosphorus pentoxide to give colourless cubes of the product (107g, 86%, melting point 115 to 7° C). Analysis: C6 H10 NO2 requires: C, 55.8%, H, 8.6%, N, 10.8%, Found: C, 54.2%, H, 8.5%, N, 10.7%.
1 2-Dimethylaminomethylacrylic acid. STR12 EXAMPLE 1 2-Dimethylaminomethylacrylic acid. STR12 Formaldehyde solution (150 ml of 40% solution) was added with stirring to a solution of dimethylamine (218g of 26% solution) and malonic acid (104g) in water (250 ml). The reaction temperature was kept at 20° C during the addition and for a further 2 hours. The solution was then heated on a steam bath for 2 hours and the water was removed under reduced pressure to give a pale yellow syrup which was dried further by azeotropic distillation with benzene. The produce was recrystallized from acetone to give colourless crystals which were dried under vacuum over phosphorous pentoxide for four days. The yield was 92g or 71%. Analysis: C6 H11 NO2 requires: N, 10.85%, Found: N, 10.70%.

With sodium carbonate In ethanol 5 Ethyl 2-dimethylaminomethylacrylate STR16 EXAMPLE 5 Ethyl 2-dimethylaminomethylacrylate STR16 A solution of the 2-dimethylaminomethylacrylic acid (35 g) compound prepared as in Example 1 in ethanol (350 ml) and concentrated sulphuric acid (60 ml) were boiled under reflux for three hours. The solution was evaporated to half volume and poured into water (1 liter). The aqueous solution was neutralised by the addition of solid sodium carbonate and extracted with ether. Evaporation of the ether solution gave a pale brown oil which was distilled to give a colourless oil (boiling point 84° C/20 mm). The product was identical with that obtained in Example 4.
