Reaction Steps

A mixture of 4,000 g of crude 2'-hydroxy-4,4'-bis(tetrahydropyranyloxy)chalcone (purity: 79.4%), 64 mg of p-toluenesulfonic acid and 12 ml of methanol was agitated at room temperature for 2 hours. The mixture was poured into 120 ml of water, and crystals which formed were filtered and washed with 250 ml of water. The crystals obtained were dried to obtain 1.836 g of 4,2',4'-trihydroxychalcone having purity of 79.4% and yield of 77.4%.
