실험 절차

To a solution of 1.6 g. of p-fluorobenzoylacetonitrile [Pihl et al., Reakts. Sposobnost Org. Soedin. Tartu. Gos. Univ., 5 (1), 27, (1968)] in 30 ml. of chloroform, cooled to -10° C., is added 1.4 g. of N,N-dimethylacetamide dimethylacetal. The reaction mixture is stirred at -10° C. for 2 hours and the evaporated in vacuo to an oil. This oil is dissolved in 150 ml. of benzene and filtered through magnesol. The filtrate is evaporated to 50 ml. and petroleum ether is added to effect crystallization. The product is collected by filtration and then recrystallized from benzene-petroleum ether with charcoal treatment giving the desired product.
