Reaction Steps

23 g of sodium hydroxide was added to 229 g of 1-(3-methyl-3-hydroxy-1-butynyl)-2,3,4-trifluorobenzene, and then stirred for 1 hour at 120° C., while acetone that is produced is distilled off using an atmospheric distillation device. This was purified by distillation under a reduced pressure (101 to 108° C./34 kPa (256 mmHg)) to obtain 110 g of 1-ethynyl-2,3,4-trifluorobenzene as an almost colorless oily material.
