A stirred suspension of 5-(3-methanesulphonyl-phenyl)-4-methyl-thiazol-2-ylamine hydrobromide (176d) (0.172 g, 0.64 mmol) in DCM (15 ml) is treated with Hunigs base (0.45 ml, 2.36 mmol) followed by ethyl-3-isocyanatopropionate (0.092 g, 0.64 mmol). The reaction mixture is stirred and heated to 60° C. for 10 hours and then the solvent in removed in vacuo. The product is purified by chromatography on silica to give the titled compound
