Participants

Reaction Steps

A mixture of 5a (4.00 g, 38.4 mmol) and trans cinnamic aldehyde (7.60 g, 57.5 mmol) in ethanol (100 ml) was heated under reflux for 3 h. After cooling to room temperature, the mixture was filtered, and the residue dried under vacuum to give 6.77 g of a white solid. Refiltration of the filtrate gave another 0.73 g of the residue and an overall yield of 91%.
