To a solution of 77 mg of 2-methyl-1-[(S)-1-(tetrahydro-furan-2-yl)methyl]-5-(2-trifluoromethoxy-phenyl)-1H-pyrrole-3-carboxylic acid in 3 ml of dimethylformamide were added 74 mg of TBTU, 179 μl of N,N-diisopropylethylamine and 26 μl of cyclohexylamine and the reaction mixture was stirred at ambient temperature for 18 hours. After such time the reaction mixture was then concentrated in vacuo and purified by column chromatography (SiO2, heptane/ethyl acetate) to give 70 mg of the title compound as a colorless solid, MS (ISP) 451.5 (M+H)+.
