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 methanesulfonyl chloride (0.02 g, 0.13 mmol) followed by pyridine (0.02 g, 0.21 mmol). The reaction was stirred at ambient temperature overnight, concentrated and purified by flash chromatography on silica gel with 20-50% EtOAc/hexane to obtain the product as white solid in 75% yield.
