Reaction Conditions

Reaction Steps

The mixture of 5 g of 2-nitro-5-chlorobenzoic acid and 15 mL of morpholine is stirred at 120° C. for 6 hours. To the reaction mixture 150 mL of ethyl acetate is added. The precipitated yellow crystalline material is filtered off, dissolved in 15 mL of water. The pH of the mixture is adjusted to 6 with acetic acid. The precipitated material is filtered off, washed with water and dried, to obtain 4.2 g of the title compound. Mp.: 172° C.
