Procedure

A solution of 2-(4-amino-phenyl)-3-cyclopentyl-N-thiazol-2-yl-propionamide (prepared in Example 3, 158 mg, 0.5 mmol) in pyridine (5 mL) at 25° C. was treated with 2,2,2-trifluoroethanesulfonyl chloride (63.5 μL, 0.57 mmol). The reaction was stirred at 25° C. for 48 h and was then concentrated in vacuo. High pressure liquid chromatography (Chromegasphere SI-60, 10 μM, 60 Å, 25 cm×23 cm ID, 40/60 heptane/ethyl acetate) afforded the 3-cyclopentyl-N-thiazol-2-yl-2-[4-(2,2,2-trifluoro-ethanesulfonylamino)-phenyl]-propionamide (98.1 mg, 42.4%) as a light yellow oil: EI-HRMS m/e calcd for C19H22F3N3O3S2 (M+) 461.1054, found 461.1064.
