To a mixture of 4′-methyl-5-(methylsulfonyl)biphenyl-3-carboxylic acid (45 mg, 0.15 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (59 mg, 0.31 mmol), 1-hydroxybenzotriazole hydrate (24 mg, 0.15 mmol), and CH2Cl2 (3 mL) were added (2-methylpyrimidin-5-yl)methanamine (29 mg, 0.23 mmol) and N,N-diisopropylethylamine (54 μL, 0.31 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; 30-60% MeCN-water[10 mM Et2NH]) to afford a white solid.
