Reaction Steps

6-(4-{[(3,4-Dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)-2-(isopropylthio)pyrimidine-4-carboxylic acid (Example 180; 200 mg, 0.423 mmol), ammonia solution (2 M in MeOH, 0.43 ml, 0.846 mmol), TEA (0.06 ml, 0.423 mmol), and HATU (161 mg, 0.42 mmol) were combined in DMF (3 ml) and stirred at room temperature for 1 h. The reaction was diluted with EtOAc and water, and the organic portion was washed sequentially with 1 N HCl, saturated sodium bicarbonate, and brine. The organic portion was dried over sodium sulfate, filtered and concentrated to give an off-white solid (312 mg). The crude material was purified by preparatory HPLC using a gradient of 40-70% acetonitrile/water (0.1% TFA) over 14 minutes to give the title compound as a white solid.
