実験手順
The compound was synthesized according to example 1 using 2-acetylbenzofuran and ethyl heptafluorobutyrate as starting materials. The product was crystallized from petroleum ether. 1H NMR (CDCl3): 6.74 (s, 1 H); 7.35 (ddd, 1H, J=0.9 & 7.2 & 8.0 Hz); 7.52 (ddd, 1H, J=1.3 & 7.2 & 8.4 Hz); 7.58-7.61 (m, 1 H); 7.68 (d, 1H, J=0.9 Hz); 7.71-7.74 (m, 1 H). IR (film): 1614 (C═O); 1232 (C—F).
