Reaction Conditions:
in nitrobenzene at 80;Friedel-Crafts Acylation;
Steps:
3 Embodiment 3
In a 1 L three-opening in the bottle, to join the nitrobenzene 500 ml, aluminum chloride/silicon dioxide (166.3 g, loading 10 wt %), stirring slowly into the acetic acid under the condition (33.0 g, 0 . 55 μM), the completion of the dropping, then gradually dripped into the pepper link (61.0 g, 0.5 μM, dissolved in 100 ml of nitrobenzene); after dropping, slow heating to 80 °C stirring reaction, until the pepper ring reaction finishes, cooling, filtering to obtain aluminum chloride/silicon dioxide catalyst; the reaction liquid layered extraction, the combined organic layer, evaporating the solvent under reduced pressure, drying to obtain products 78.8 g, yield 96%.
