Reaction Steps

1,3,5-tris(2,2-dimethoxy-1,3-dioxoindan-5-yl)benzene (26) (101 mg, 0.146 mmol) was suspended in a solvent mixture of 2 ml of acetic acid and 2 ml of water, and the suspension was mixed with 2 ml of 47% hydrobromic acid. The mixture was refluxed at 110° C. for 1.5 hours. After it was cooled to room temperature, the reaction solution was diluted with water, and the resulting solid was filtered and dried, to obtain 77.3 mg (87%) of 1,3,5-tris(2,2-dihydroxy-1,3-dioxoindan-5-yl)benzene (27) in the form of a gray solid. The readings for this compound are as follows.
