Diisopropylethylamine → 4'-Methyl-5-(methylsulfonyl)-N-((6-(trifluoromethyl)pyridin-3-yl)methyl)biphenyl-3-carboxamide

Participants

Reaction Steps

To a mixture of 4′-methyl-5-(methylsulfonyl)biphenyl-3-carboxylic acid (40 mg, 0.14 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (53 mg, 0.28 mmol), 1-hydroxybenzotriazole hydrate (21 mg, 0.14 mmol), and CH2Cl2 (3 mL) were added C-(6-trifluoromethyl-pyridin-3-yl)-methylamine (36 mg, 0.21 mmol) and N,N-diisopropylethylamine (48 μL, 0.28 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; 40-80% MeCN-water[10 mM Et2NH]) to afford a white solid.
