Versuchsvorschrift
To the solution of 2-methoxymethoxy-5-(trifluoromethyl)benzyl alcohol (3.15 g) from Example 60 in methanol (20 ml) was added 10% H2SO4 (5 ml) for reflux under heating for 1 hour. The solvent was removed under reduced pressure. To the residue was added water, the aqueous layer was extracted with ether. The ether layer was washed with water and saturated sodium chloride solution, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, to give the title compound (2.5 g; 98%).
