Reaction Steps
A mixture of 5.0 g of 7-hydroxy-3,4-dimethylcoumarin, 5.4 g of 4-bromobenzyl chloride, 5.4 g of K2CO3 and 100 ml of acetone was stirred for 4 days at room temperature and evaporated down, and the residue was partitioned in H2O/methylene chloride. After the organic phase had been separated off, extraction was carried out twice with methylene chloride, the combined organic phases were evaporated down and the residue was recrystallized from methanol.
