To an ice-cold solution of 2-(4-(((tert-butyldimethylsilyl)oxy)methyl)phenyl)-5-ethyl-1,3,4-oxadiazole (3.0 g, 9.4 mmol) in MeOH (30 mL) was added 1 M HCl (20 mL, 20 mmol) dropwise. The reaction was stirred over ice for 1 hr then concentrated. The residue was quenched with saturated aqueous NaHCO3 and extracted with EtOAc. The combined organics were dried over Na2SO4 and concentrated in vacuo to give (4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenyl)methanol as an off-white solid (1.92 g, 93% yield).
