実験手順
The title compound was prepared according to the method described in example 1b starting from 3-bromo-5-ethoxy-4-hydroxy-benzaldehyde (6 g), 3-aminocrotonitrile (2.01 g) and 5-propylcyclohexane-1,3-dione (3.8 g). The reaction mixture was cooled (0° C.) and the title compound was filtered off and washed with ethanol (cold). Yield: 6.3 g. MS-ESI: [M+H]+=445/447
