Reaction Steps
To a solution of methyl [4-(8,8-dimethyl-5-oxo-5,6,7,8-tetrahydro-naphthalen-2-yl-ethynyl)-phenyl]-acetate (Compound 4) in 5 mL MeOH at 0° C. was added NaBH4 (18.0 mg, 0.48 mmol). The reaction was stirred at 0° C. for 2 hours and then quenched by the addition of H2O. The solution was diluted with Et2O and washed with H2O and saturated aqueous NaCl before being dried (MgSO4) and the solvents were removed under reduced pressure. Column chromatography (20-40% EtOAc-hexanes) afforded 140.0 mg (87%) of the title compound as a colorless oil.
