Procedure
To a cooled solution of 4-methoxy-2-aminobenzamide (5.6 g, 33.7 mmol), 4-isopropyl-thiazole-2-carboxlic acid (7.1 g, 42 mmol) and Hobt-hydrate (6.4 g, 42 mmol) in DMF (150 ml) was added EDAC (8.6 g, 45 mmol) and TEA (6.4 ml, 45 mmol) and the mixture was stirred overnight at room temperature. A 2.5% aqueous solution of citric acid (600 ml) was added and the mixture was extracted three times with ethyl acetate. The organic phase was washed with brine and saturated sodium hydrogencarbonate. The solution was dried over sodium sulfate and evaporated under reduced pressure.
