Pyrrolidine → 4'-Methyl-N-((2-methylpyrimidin-5-yl)methyl)-5-(pyrrolidine-1-carbonyl)biphenyl-3-carboxamide

Participants

Reaction Steps

To a mixture of 4′-methyl-5-((2-methylpyrimidin-5-yl)methylcarbamoyl)-biphenyl-3-carboxylic acid (11 mg, 0.030 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (12 mg, 0.061 mmol), 1-hydroxybenzotriazole hydrate (4.7 mg, 0.030 mmol), and CH2Cl2 (2 mL) were added pyrrolidine (3.2 mg, 0.046 mmol) and N,N-diisopropylethylamine (11 μL, 0.061 mmol). The mixture was stirred at room temperature overnight, and then concentrated in vacuo. The residue was purified by preparative HPLC (100×21.2 mm C18 column, 30-70% MeCN/water[10 mM Et2NH]) to afford a white foam.
