Triethylamine → 4-(Tert-butyldimethylsilyloxymethyl)pyridine

Participants

Reaction Steps

To a solution of pyridin-4-ylmethanol (21.8 g, 0.20 mol) in CH2Cl2 (200 mL) were added Et3N (30.0 g, 0.30 mmol) and TBSCl (45.0 g, 0.30 mmol) at 0° C. The reaction mixture was stirred at room temperature for 4 h, then quenched with water. The organic phase was separated, and the aqueous layer was extracted with CH2Cl2. The combined organic layers were washed with brine, dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography to afford 4-((tert-butyldimethylsilyloxy)methyl)-pyridine.
