実験手順
The solution of 2-methoxymethoxy-5-(trifluoromethyl)benzaldehyde (3.3 g) from Example 59 in anhydrous methanol (20 ml) was cooled in an ice bath, followed by gradual addition of NaBH4 (0.53 g). After stirring at room temperature for 15 minutes, the solvent was removed under reduced pressure. To the residue was added water, and 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 an colorless oil compound as the title compound (3.15 g; 95%).
