Versuchsvorschrift

The reaction product (XV) obtained in accordance with Example 16 is suspended in warm ethanol. A clear solution is formed, following the addition of 5 ml of 5% aqueous hydrochloric acid. 10 ml of water are added and the aqueous solution is extracted by repeated shaking with 10 ml batches of chloroform. After the chloroform has been distilled off in vacuo from the combined chloroform extracts, 2-hydroxy-4-dimethylaminobenzaldehyde (XVI) is obtained in the form of pale yellow needles, melting at 77° to 78° C.
