実験手順
A mixture of 3-ethyl-1-fluoro-5-methylbenzene (1.1 g, 0.008 mol), paraformaldehyde (1.5 g, 0.05 mol), hydrobromic acid (4.1 ml 0.017 mol) (4.1 M in acetic acid) and acetic acid (2.5 ml) was stirred at ambient temperature for 40 h. To the mixture were water and petroleum ether (40-60) added and the organic layer was separated, washed with water, dried over anhydrous sodium sulfate and evaporated carefully under reduced pressure. The desired product was obtain as a yellow oil (1.3 g, 72%).
