Reaction Steps

1-(2-(3,5-dimethylisoxazol-4-yl)-1-(4-methoxyphenyl)-1H-indol-3-yl)-2,2,2-trifluoroethanone was dissolved in dry DCM and the mixture was cooled on an ice-bath under an atmosphere of nitrogen. BBr3 (17 μl, 0.1 mmol) was added and the temperature was allowed to warm to RT and the mixture was stirred over night. Water, DCM and some dioxane were added, the phases were separated and the solvents were evaporated. The residue was passed through a short plug of silica with EtOAc as eluent. The residue was purified by preparative HPLC to provide the title compound 1-(2-(3,5-dimethylisoxazol-4-yl)-1-(4-hydroxyphenyl)-1H-indol-3-yl)-2,2,2-trifluoroethanone in 46% yield. ES/MS m/z: 401.1 (M+H), 399.1 (M−H); 1H NMR (methanol-d4, 500 MHz): 8.26 (m, 1H), 7.41-7.34 (m, 2H), 7.18 (m, 1H), 7.11 (m, 2H), 6.89 (m, 2H), 2.19 (s, 31-1) and 2.01 (s, 3H).
