실험 절차
The following morning thin-layer chromatography showed only a trace presence of the dibromonaphthalic anhydride. The reaction mixture was cooled to room temperature followed by the addition of 350 ml of ether. The triethylamine hydrobromide byproduct was removed by filtration. The filtrate was concentrated on the rotary evaporator, to give the diphenylethynyl derivative of the 1,8-naphthalic anhydride.
