Participants

Reaction Steps

To a mixture of 4′-methyl-5-(2-oxopiperidin-1-yl)biphenyl-3-carboxylic acid (45 mg, 0.14 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (56 mg, 0.29 mmol), 1-hydroxybenzotriazole hydrate (22 mg, 0.14 mmol), and CH2Cl2 (3 mL) were added (R)-1-(6-methylpyridin-3-yl)ethanamine hydrochloride (38 mg, 0.22 mmol) and N,N-diisopropylethylamine (51 μL, 0.29 mmol). The mixture was stirred at room temperature overnight and then concentrated. The residue was purified by preparative HPLC (100×20.2 mm, C18 column; 30-80% CH3CN-water [10 mM Et2NH]) to afford a white foam.
