Procedure

2-[(4′-Trifluoromethyl-biphenyl-2-carbonyl)-amino]-quinoline-6-carboxylic acid (F-1a2, 1.2 g, 2.53 mM), EDC (0.79 g, 6.34 mM), HOBT (0.86 g, 6.34 mM) and (S)-2-amino-N-pentyl-2-phenyl-acetamide hydrochloride (0.78 g, 3.05 mM,) were combined and dissolved in THF (12.5 mL). The mixture was treated with diisopropylethylamine (2.20 mL, 13 mM) and stirred at room temperature for 16 h. The mixture was diluted with CH2Cl2 and washed with water. The CH2Cl2 fraction was dried (Na2SO4), filtered and concentrated. The product was purified by flash chromatography, eluting with 30% acetone in hexanes to give 1.36 g of (S)-2-[(4′-trifluoromethyl-biphenyl-2-carbonyl)-amino]-quinoline-6-carboxylic acid (pentylcarbamoyl-phenyl-methyl)amide as an amorphous solid.
