Reaction Steps

The compound was prepared as described in Example 3 by adding 3-methoxy-4-hydroxy-5-nitrocinnamaldehyde (22 mg, 0.1 mmol) to N-(cyanoacetyl)3,4-dihydroxybenzylamide (21 mg, 0.1 mmol). After refluxing for 4 h and recrystallization from ethanol-water an orange solid was obtained (19 mg, 46%). The product gave the following analytical data:
