Reaction Steps
To a mixture of 2-hydroxy-3-chloropyrido[1,2-a]pyrimidine-4-one (0.324 g), and methyltriazabicyclodecene (0.24 mL) in DMF (15 mL) was added 2-bromomethylsaccharin (0.414 g). The mixture was stirred overnight, poured into water and the precipitate which formed was collected by filtration and recrystallized from DMF to afford 0.371 g (65%) of 2-[3-chloro-4-oxo-4H-pyrido[1,2-a]pyrimidine-2-yl]oxymethyl-saccharin.
