Versuchsvorschrift

To a well stirred mixture of 84.35 g (0.484 mol) of dimethyl acetonedicarboxylate, 200 ml of saturated sodium acetate, and 400 ml of ethanol at 70° C. was passed 49 g of trifluoroacetonitrile in 4 hours. The reaction mixture was cooled and poured into a mixture of 100 ml of concentrated HCl and 1000 g of ice. The insoluble material was collected to give 28.7 g (25%) of product: mp 235°-238.5° C. (dec).
