실험 절차

Add tetrabutylammonium fluoride (2.13 mL, 2.13 mmol, 1M solution in THF) to a solution of 2-(tert-butyldimethylsilyloxymethyl)-5-(3-methyl-butyryl)-pyridine (330 mg, 1.066 mmol) in anhydrous THF (20 mL) at 0° C. and stir at this temperature for 1 h. Concentrate the solvent in vacuo and purify the crude mixture by chromatography on silica gel eluting with EtOAc to provide the desired intermediate (327 mg, 100%).
