실험 절차

To a stirred mixture of 2.5 parts of 4-fluoro-2-(phenylmethoxy)phenol, 2.3 parts of 1-bromo-3-chloropropane, 10 parts of water and 0.39 parts of tetrabutylammonium hydrogen sulfate was added dropwise a solution of 0.7 parts of sodium hydroxide in 5 parts of D at 60° C. (exothermic reaction: temperature rose to 70°). The whole was stirred for 2 hours at 70° C. After cooling, the product was extracted twice with methylbenzene. The combined extracts were dried, filtered and evaporated, yielding 3.4 parts (100%) of 1-(3-chloropropoxy)-4-fluoro-2-(phenylmethoxy)benzene as a residue (intermediate 78).
