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 methanesulfonyl chloride (50 μL, 0.57 mmol ). The reaction was stirred at 25° C. for 7 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 3-cyclopentyl-2-(4-methanesulfonylamino-phenyl)-N-thiazol-2-yl-propionamide (98.2 mg, 49.9%) as a tan solid: mp 85-90° C.; EI-HRMS m/e calcd for C18H23N3O3S (M+) 393.1180, found 393.1185.
