Reaktionsschritte
A solution of 19.31 g of ethyl trifluoroacetoacetate (Fairfield Chemical) in 50 ml of ethyl acetate was hydrogenated at atmospheres on a Parr shaker over (0.5 g) PtO2 as a catalyst. The volatiles were removed and the residue distilled under high vacuum to afford 14.75 g (76%) of the title compound as a low melting solid. bp=47°-49° C. at 0.1 mm of Hg, mp (uncorrected)=about 25° C.
