Procedure

To a solution of {2-[3-(2-cyclopentanecarbonyl-4-methyl-phenyl)-ureido]-thiazol-4-yl}-acetic acid ethyl ester (0.05 g, 0.12 mmol) in 2 ml of acetonitrile was added N-chlorosuccinimide (0.018 g, 0.13 mmol). The reaction mixture was stirred under nitrogen in a pressure bottle excluded from light for 1.5 hour at 80° C. The mixture was diluted with 15 ml of DCM, washed (1N HCl, saturated NaHCO3, water), dried (MgSO4) and concentrated under reduced pressure. The crude product was purified by preparative HPLC to afford the title compound (0.08 g, 15%).
