Reaction Steps
500 ml of anhydrous ethyl ether are run gently onto 26 g of lithium aluminum hydride, and 100 g of niflumic acid, dissolved in 250 ml of anhydrous tetrahydrofuran, are then added dropwise. The mixture is then brought to reflux for 3 hours. After cooling, it is hydrolyzed with 150 ml of ethyl acetate and 100 ml of saturated sodium sulfate solution. After filtration, the filtrate is concentrated to obtain the expected compound in the form of a yellow solid.
