2-(3-Pyridyl)thiazole-4-carboxylic acid (206 mg, 1 mmol) and 2-amino-benzamide (163 mg, 1.2 mmol) are mixed, and chloroform (10 ml) and pyridine (1.2 ml) are added. Then 1-hydroxybenzotriazole hydrate (230 mg) and 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-P-toluene-sulphonate CAS[2491-17-0] (635 mg) are added, and the mixture is stirred at room temperature for 20 h. The solid is filtered off with suction and washed with ethyl acetate, water and again with ethyl acetate. Purification of the solid by preparative HPLC results in Example 1.1 as a white foam (58 mg).
