Reaction Steps

A mixture of mefenamic acid (2.41 g, 0.01 mole), 2-chloro-N,N-dimethylacetamide (1.6 g, 0.013 mole), triethylamine (1.6 ml, 0.011 mole) and sodium iodide (0.15 g, 0.001 mole) in N,N-dimethylformamide (10 ml) was stirred at 90° C. for 2 h. Water (50 ml) was added and the mixture allowed to stand at 4° C. for 5 h. The title compound was isolated by filtration, washed with water and recrystallized from ethanol-water (3.0 g, 92%). Mp 85°-86° C.
