실험 절차

1,1-Dimethylethyl 5-cyano-2-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (Intermediate 2, 2.77 g, 8.90 mmol) was dissolved in DCM (40 mL), treated with TFA (10 mL) and the resulting mixture was stirred at room temperature for 4 hours. The solvent was removed under reduced pressure to give the title compound as a brown solid (2.49 g);
