500 mg (1.53 mmol) of trans-3-nitrocinnamic acid-N-(2-methoxycarbonyl-phenyl)-amide are stirred into a mixture of 20 ml of methanol and 8 ml of 2N sodium hydroxide solution for two hours at 50° C. Then the methanol is distilled off in vacuo, the residue is diluted with about 150 ml of water and adjusted to about pH 2.5 with stirring.
