Versuchsvorschrift

75.5 g (500 millimoles) of 3-nitrobenzaldehyde and 73 g (550 millimoles) of dimethyl malonate were stirred for 4 hours at 60° C., similarly to Example 9. After the addition of 5 ml of glacial acetic acid, the mixture was worked up in a conventional manner. The product of melting point 78°-80° C. was obtained in 96% yield.
