Methyl iodide → N-[6-(4-Fluorobenzyl)-4-methoxy-5-oxo-5,6,7,8-tetrahydro-2,6-naphthyridin-1-yl]-N-methylmethanesulfonamide

Participants

Reaction Steps

To a solution of N-[6-(4-fluorobenzyl)-4-methoxy-5-oxo-5,6,7,8-tetrahydro-2,6-naphthyridin-1-yl]methanesulfonamide (0.097 g, 0.256 mmol) in DMF (2 mL) was added Cs2CO3 (0.083 g, 0.256 mmol) and MeI (0.04 g, 0.28 mmol, dissolved in DMF). After stirring for 2 hours, additional MeI (0.02 g, 0.14 mmol) was added. The product mixture was concentrated. The residue was partitioned between CHCl3 and pH 7 buffer. The organic extract was dried with Na2SO4, filtered, and concentrated under vacuum to provide the title compound.
