To a solution of 4-formyl-3-isopropyl-phenyl 1,1,1-trifluoro-methansulfonate (Intermediate 148, 540.0 mg, 1.82 mmols) in 7 mL MeOH at 0° C. was added NaBH4 (72.0 mg, 1.91 mmols). After stirring 2 hours at 0° C. the reaction was carefully quenched with H2O and extracted with Et2O. The combined organic layers were washed with H2O and saturated aqueous NaCl, dried (MgSO4), and concentrated under reduced pressure. The title compound was isolated by column chromatography (5-10% EtOAc—hexanes) as a colorless oil, 355.0 mg (90%).
