Participants

Reaction Steps

Diisopropylethylamine (0.043 ml, 0.25 mmol), HATU (0.048 g, 0.12 mmol) and HOAT (0.017 g 0.12 mmol) were added to a stirred solution of 2-chloro-6-(4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)isonicotinic acid (Example 153; 0.055 g, 0.12 mmol) in DMF (2 ml). The resultant solution was stirred for 5 mins and hydrazine (0.04 ml, 0.12 mmol) was added. The mixture was stirred at room temperature for 14 h, partitioned between water and EtOAc. The layers were separated and the organic layer was washed with water two more times. The organic phase was dried over magnesium sulfate and concentrated to give the title compound (30 mg).
