Reaction Steps

To a 250 ml reactor were added 12.5 (0.08 mol) of 2-ethoxy-3-fluorophenol [F1], 3.2 g (0.08 mol) of sodium hydroxide and 20 ml of ethanol. After cooling to around 10° C., 20 ml of an ethanol solution of 9.6 g (0.088 ml) of bromoethane was slowly added. After the termination of the addition, they were reacted under a reflux temperature for 3 hours and, after the termination of the reaction, dichloromethane was added, followed by extraction. The extraction liquid was washed with water and dried, and the solvent was removed by distillation to obtain 11.0 g of an oily product [G1]. The process yield was 75%.
