Reaction Steps

To a solution of 4-nitro-o-aminophenol (15.4 g, 0.1 mole) in 200 ml of ethanol, 3-methyl-2-thiophene carboxaldehyde (12.6 g, 0.1 mole) is added at room temperature. The mixture is allowed to stir for 1 hour and the precipitated yellow Schiff's Base is collected. Crystallization from acetonitrile yields 24.1 g of product, melting point 169°-171°C.
