Reaction Steps

5-Cyano-2-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid (Intermediate 3, 2.49 g, 9.76 mmol) was dissolved in water (36 mL) and N-methyl-2-pyrrolidone (48 mL). The resulting mixture was heated at 120° C. for 18 hours. The reaction mixture was allowed to cool to room temperature and diluted with water. The resulting precipitate was collected by filtration, washed with water and dried under high vacuum at 40° C. for 5 hours to give the title compound as a white solid (1.26 g);
