Reaction Steps
To a solution of 6-(benzyloxy)pyridin-3-ol (2.0 g, 10 mmol, 1 eq.) in DMF (20 mL) was added NaH (60% in mineral oil; 0.6 g, 15 mmol, 1.5 eq.) at 0-5° C. portion-wise. Upon the completion of addition, the mixture was continued to stir at 0-5° C. for 15 min, added chloromethyl methyl ether (0.88 g, 11 mmol, 1.1 eq.), stirred at 0-5° C. for another 20 min, and quenched with NH4Cl(sat) solution. The aqueous layer was extracted with EtOAc (3×20 mL) and the combined organic layers were washed with water and brine, dried over Na2SO4, concentrated, and purified on silica gel using 25% EtOAc/hexanes as eluent to give 2-(benzyloxy)-5-(methoxymethoxy)pyridine (2.1 g, 87%) as a colorless oil. MS (ESI) m/z 246.1 [M+H]+.
