Procedimiento

The compound (b5) was added dropwise to a reactor having 1,200 g of a 10% sodium hydroxide aqueous solution placed therein over 30 minutes in a temperature range of 20 to 40° C. Thereafter, 462 g of diethyl sulfate was added dropwise thereto over 1 hour in a temperature range of 25 to 35° C., followed by stirring for 5 hours in that temperature range. The resulting organic layer was collected and washed with 200 mL of water in three times, followed by drying, to obtain 505 g of 1-chloro-3-ethoxy-2-fluorobenzene (b44). The resulting liquid was colorless.
