Reaction Steps

N-[1-(4-Acetyl-6-chloropyridin-2-yl)piperidin-4-yl]-3,4-dichloro-5-methyl-1H-pyrrole-2-carboxamide (Example 115) (49 mg, 0.114 mmol) was dissolved in EtOH (2 ml). Pyridine (74 μl, 0.913 mmol) was added followed by hydroxylamine hydrochloride (63.4 mg, 0.913 mmol). The mixture was stirred at room temperature overnight. The product was purified by semi-prep reverse phase HPLC eluting with CH3CN/H2O (0.1% TFA). (28 mg).
