-13 °C

To a chilled (-15°C.) reaction vessel there was added: anhydrous dimethylamine (100 grams); ethyl acrylate (250 grams); phenothiazine (0.5 gram); and p-methoxyphenol (0.5 gram). The mixture was maintained at -13°C. for 2 hours with stirring after which the temperature was allowed to rise to about 25°C. Unreacted dimethylamine and ethyl acrylate were removed by distillation. The product was recovered by distillation at 58°C. and 10 mm. mercury pressure in a yield of 97 percent. The product, designated herein as Amine Catalyst VIII, has the formula, (CH3)2NCH2CH2C(O)OC2H5, as verified analytically by infrared spectroscopy.
