To a solution of (2-{[(3-chloro-2-methylphenyl)sulfonyl]amino}-1,3-thiazol-5-yl)acetic acid (Example 3) (0.09 g, 0.25 mmol) in CH2Cl2 (5.0 mL) and DMF (0.5 mL) were added EDCI (0.05 g, 0.27 mmol), DMAP (0.02 g, 0.12 mmol), triethylamine (0.1 mL, 0.75 mmol) and diisopropylamine (0.04 mL, 0.30 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was then washed with 1 M HCl (2×15 mL) and the organic layer was collected. The organic phase was dried (MgSO4) and concentrated under reduced pressure. Purification using preperative HPLC afforded the desired product (0.01 g) in 9% yield.
