Procedure

In 15 ml of ethanol, 1.8 g of 1,1,1-trifluoro-2-octyl 4-benzyloxybenzoate prepared in the reaction step [3] mentioned above was dissolved and 0.3 g of Pd-carbon was further added. The mixture was stirred at an ambient temperature for a whole day and night under a hydrogen gas atmosphere. After the Pd-carbon was filtered off, the solvent was distilled off at a reduced pressure to obtain 1.4 g of the objective compound.
