Reaction Steps

To a solution of 80 mg (0.94 mmol) piperidine in dioxane (1 ml) 2M trimethylaluminium solution in heptane (0.94 mmol, 0.47 ml) was carefully added. The solution was stirred at room temperature for 1 hour. A suspension of 100 mg (0.27 mmol) ({2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazol-4-yl}-acetic acid ethyl ester in dioxane (3 ml) was added and the reaction was refluxed over night. Water was added carefully and the reaction was extracted twice with ethyl acetate. The organic layer was dried over sodium sulphate, filtered and the solvent was evaporated under reduced pressure to yield 110 mg (99%) 2-{2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazol-4-yl}-1-piperidin-1-yl-ethanone as a brown foam.
