To a solution of 3-{[tert-butyl(dimethyl)silyl]oxy}-5-(3-methoxypropyl)benzaldehyde from the previous step (1 eq.) in THF (0.2 M) was added tetrabutylammonium fluoride (1.0 M THF solution, 1.1 eq.). The resulting reaction mixture was then stirred at RT for 30 min. The reaction was quenched sat. aq. NH4Cl and then extracted with ether. The combined organic extracts were washed with water and brine, dried over MgSO4, filtered and the filtrate concentrated in vacuo. Further purification of the crude product thus obtained by way of column chromatography (SiO2, Hex→3:2 (v/v) Hex:EtOAc) afforded the title compound as a pale yellow oil.
