실험 절차

2-(3,5-Dimethylisoxazol-4-yl)-1-(4-hydroxyphenyl)-1H-indole-3-carbimidate (Example 184) was dissolved in EtOH and 10 eq hydrazine was added. The resulting mixture was stirred at 90° C. for 10 hours. The reaction mixture was diluted with EtOAc and washed with brine. The organic phase was evaporated to dryness in vacuo and then purified using reversed phase preparative HPLC. Fractions were combined, concentrated and the final product was identified by 1H-NMR and LC/MS. Purity was determined by analytical HPLC. ES/MS m/z: 362.21 (M+H), 360.28 (M−H); 1H NMR (methanol-d3, 500 MHz): 7.81 (m, 1H), 7.36-7.32 (m, 3H), 7.08 (m, 2H), 6.90 (m, 2H), 2.16 (s, 3H) and 1.96 (s, 3H).
