実験手順
At 0° C., 10 eq of boron trifluoride-dimethyl sulfide was added to 4-[3-bromo-1-(4-methoxyphenyl)-1H-indol-2-yl]-3,5-dimethylisoxazole (the intermediate product of step (b) from the synthesis of Example 22), dissolved in DCM and stirred at ambient temperature over night. The mixture was diluted with EtOAc and washed with brine, the organic phase was concentrated and subjected to reversed phase preparative HPLC. Appropriate fractions were combined and evaporated, and identified by ES/MS m/z: 385.1 (M+H), 383.09 (M−H) and 1H NMR (acetone-d6, 500 MHz): 7.60 (m, 1H), 7.31-7.23 (m, 3H), 7.17 (m, 2H), 6.95 (m, 2H), 2.28 (s, 3H) and 1.99 (s, 3H).
