Participants

Reaction Steps

A solution of KOH 50% (3 ml) is added to an equimolar solution of 3-(2-methylallyloxy -4acetyl-xanthen-9-one (2.31 g, 0.0075 mol) and 2,6dichloro-benzaldehyde (1.31 g, 0.0075 mol) in ethanol 95%; the addition is performed under energetic stirring at room temperature. The reaction is left under stirring for one night and then diluted with water and acidified; the precipitate is separated by filtration and dried under vacuum. The compound is crystallized by methanol to give 2.1 g of product m.p. 135-137° C., 1H-NMR (CDCl3)δ:4.74 (m, 2H), 5.4 (m, 2H), 5.95 (m, 1H), 7.06-8.5 (m, 11 H).
