Reaction Steps
5-(2-Chloro-5-trifluoromethyl-phenyl)-6-cyclopentyloxy-3-pyridinecarboxylic acid (0.14 g, 0.3 mmol) was dissolved in DMF (5 mL). To the solution was added TBTU (0.12 g, 0.4 mmol), N,N-diisopropylethyl amine (0.3 mL, 1.7 mmol) and (1R,2R)-2-amino-cyclohexanol (58 mg, 0.4 mmol). The reaction mixture was stirred for 18 h at room temperature. The solvent was evaporated in vacuo and the residue was purified by column chromatography on silica (n-heptane/ethyl acetate gradient) to yield 0.11 g of the title compound as a colorless solid oil, MS (ISP) 483.4 (M+H)+.
