Reaktionsschritte

0.315 mol of each of 4-bromo-2-fluorophenol (1), 1-butanol and triphenylphosphine were dissolved in 1000 ml of tetrahydrofuran, and 0.315 mol of diisopropyl azodicarboxylate was added dropwise at about 20° C. After the mixture had been stirred overnight, the solvent was removed by distillation in a rotary evaporator, and the residue was subjected to conventional work-up, giving the compound (2) in a yield of 95.6% of theory.
