Versuchsvorschrift

A solution of 27.80 g (0.28 mol) N,N-di-n-propylamine was added dropwise to a solution of 20.00 g (0.24) diketene in 100 ml MeOH at 0° C. After stirring for 3 hours at 0° C., no starting material was detected anymore by thin-layer chromatography. The reaction mixture was spun off and the residue was purified by means of column chromatography. 38.05 g of product was obtained as a slightly yellow oil.
