90 mg (0.2 mmol) [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-(4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-yl)-amine trihydrochloride and 33 mg (0.2 mmol) 4-fluorobenzoyl chloride were suspended in methylene chloride (2 ml) and 101 mg (1 mmol) triethyl amine was added at room temperature. The reaction was stirred over night, diluted with methylene chloride, washed once with water, once with brine, dried over sodium sulphate, filtered and the solvent was evaporated under reduced pressure. The reaction was purified on silica gel with methylene chloride/methanol 19/1 yielding 52 mg (56%) (4-fluoro-phenyl)-{2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-6,7-dihydro-4H-thiazolo[5,4-c]pyridin-5-yl}-methanone as a yellow solid.
