Participants

Reaction Steps

6-Butoxy-5-(2-fluoro-5-trifluoromethyl-phenyl)-nicotinic acid (0.10 g, 0.3 mmol) was dissolved in DMF (5 mL). To the solution was added TBTU (0.10 g, 0.3 mmol), N,N-diisopropylethyl amine (0.24 mL, 1.4 mmol) and (1R,2R)-2-amino-cyclohexanol (47 mg, 0.3 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 78 mg of the title compound as a light yellow solid, mp 172–178° C., MS (ISP) 455.3 (M+H)+.
