Reaction Steps

To a solution of 4-(1-Isopropyl-piperidin-4-ylcarbamoyl)-1H-pyrrole-2-carboxylic acid benzyl ester (50 mg) in DMF (2 mL) was added Cs2CO3 (176 mg), followed by 2-bromo-N-(5-chloro-pyridin-2-yl)-acetamide (34 mg). The mixture was stirred for 20 h at RT whereupon it was filtered. The filtrates were directly subjected to preparative HPLC(CH3CN/H2O gradient+0.05% TFA). Pure 1-[(5-chloro-pyridin-2-ylcarbamoyl)-methyl]-4-(1-isopropyl-piperidin-4-ylcarbamoyl)-1H-pyrrole-2-carboxylic acid benzyl ester (28.5 mg) was obtained as its trifluoroacetate salt. MS (ESI+): m/e=538 [M+H]+, chloro pattern.
