Participants

Reaction Steps

The compound was prepared as described in Example 3 by adding 3,5-dimethoxy-4-hydroxycinnamaldehyde (0.15 g, 0.72 mmol) to 2-cyanothioacetamide (0.073 g, 0.72 mmol). After refluxing for 1 h the residue was purified on a TLC-plate in hexane-ethyl acetate, 1:1 to give a red solid (0.10 g, 52%). The product gave the following analytical data:
