Reaction Steps

70 mg of 4-(6-hydroxyquinolin-2-yl)-3-methoxybenzoic acid (Compound 48) was suspended in 10 ml DCM and 0.25 ml BBr3 was added. The mixture was stirred at room temperature for 2 days. 20 ml water was added to quench the reaction. DCM was removed by evaporation and the precipitate was filtered and washed with water and dried to obtain 29 mg of 3-hydroxy-4-(6-hydroxyquinolin-2-yl)benzoic acid. 1H NMR (DMSO-d6 300 MHz TMS): δ 10.34 (s, 1H), 8.45 (d, 1H), 8.30 (d, 1H), 8.24 (d, 1H), 7.97 (d, 1H), 7.46 (m, 3H), 7.26 (d, 1H), MS (ESI): m/z=282.30 [M+1]+.
