Triethylamine → N-(3-((3-((1H-pyrrolo[2,3-b]pyridin-4-yl)methyl)ureido)methyl)phenyl)-3-cyclopentylpropiolamide

Participants

Reaction Steps

To a solution of (1H-pyrrolo[2,3-b]pyridin-4-yl)methanamine (198 mg, 1.345 mmol) in tetrahydrofuran (6 mL) were added triethylamine (0.563 mL, 4.04 mmol) and carbonyldiimidazole (327 mg, 2.018 mmol), and the mixture was stirred at room temperature for 18 h. N-(3-(aminomethyl)phenyl)-3-cyclopentylpropiolamide (326 mg, 1.345 mmol) was added and the mixture was stirred at room temperature for 18 h. The mixture was quenched with water (10 mL) and extracted with EtOAc (3×). The extract was dried (Na2SO4) and concentrated. The residue was purified using reverse-phase HPLC. The fractions containing the product were combined and concentrated. The residue was washed with 10% NaHCO3 and dried under vacuum to give 185 mg of product (N24229-78-A1)) as a white solid.
