반응 단계
7.3 ml (0.05 mol) of ethyl 3-oxo-4,4,4-trifluoroacetoacetate, 6 g (0.073 mol) of CH3COONa, 20 ml of water, 37.5 ml of ethanol and a solution of 0.05 mol of phenyldiazonium chloride were treated as described in preparation 2. The crude product was purified by chromatography on silica gel (hexane/Et2O 0%→25%) obtaining 8.65 g of the title compound. M.p.=78°-80° C.
