2-bromo-1-(ethoxymethyl)-4-fluorobenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the method of Example 2, Step D, 7.18 g (0.0308 mole) of ethyl 2-bromo-4-fluoro benzyl ether, 2 ml of fuming nitric acid, and 18 ml of concentrated sulfuric acid were reacted in 20 ml of 1,2-dichloroethane, yielding 3.1 g of ethyl 2-bromo-4-fluoro-5-nitrobenzyl ether.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the method of Example 1, Step A, 10.9 g (0.041 mole) of 2-bromo-4-fluorobenzyl bromide and 18.2 ml of a 21% by weight solution of sodium ethoxide in ethanol were reacted in 50 ml of tetrahydrofuran, yielding 7.18 g of ethyl 2-bromo-4-fluorobenzyl ether.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
