Mode opératoire

To a reaction vessel was added the crude residue of (S)-1-(4-(5-chloropyridin-3-yl)-6-cyano-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridin-2-yl)pyrrolidine-2-carboxylic acid (0.030 g, 0.063 mmol), propylphosphonic anhydride (0.10 mL, 50% w/w in DMF), and N-methylethanamine (0.0037 g, 0.063 mmol) suspended in DMF (0.5 mL). The reaction was stirred at ambient temperature for 6 hours. The reaction was diluted with H2O (2.0 mL) and was extracted with EtOAc (2×5 mL). The combined organics were concentrated in vacuo to afford (S)-1-(4-(5-chloropyridin-3-yl)-6-cyano-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridin-2-yl)-N-ethyl-N-methylpyrrolidine-2-carboxamide as a crude residue. MS ESI calc'd. for C28H34ClN7O [M+H]+ 520. found 520.
