Procedure

To 1-[4-(amino-ethyl)-thiazol-2-yl]-3-(2-cyclopentanecarbonyl-4-methyl-phenyl)-urea (0.05 g, 0.13 mmol) in 10 mL DCM at 0° C. was added acetyl chloride (0.02 g, 0.27 mmol) followed by pyridine (0.02 g, 0.21 mmol). After stirring for 3 h, reaction was concentrated and purified by flash chromatography on silica gel with 50% EtOAc/hexane to obtain the product in 64% yield.
