The mixture of 8-Methyl dihydrocoumarin (20 gm, 0.123 mole) and Aluminum trichloride (49.3 gm, 0.370 mole) was stirred for 2 hours at 175-180° C. To the reaction mixture, water (250 ml) was added slowly and stirred for an hour. Further it was filtered and obtained solid was stirred in Methanol (60 ml). Finally the suspension was filtered and obtained solid was dried under vacuum to give 13.5 gm of desired product as a solid.
