Example L Isoxazole-5-carboxylic acid [2-(2-o-tolyl-chroman-6-yloxy)-thiazol-5-ylmethyl]-amide To a solution of [2-(2-o-tolyl-chroman-6-yloxy)-thiazol-5-ylmethyl]amine (150 mg, 0.43 mmol) in DMF (2 ml), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (114 mg, 0.60 mmol, 1.4 eq), 1-hydroxy-benzotriazole (81 mg, 0.60 mmol, 1.4 eq) and N-methylmorpholine (107 mg, 1.07 mmol, 2.5 eq) and isoxazole-5-carboxylic acid (72 mg, 0.64 mmol, 1.5 eq) were added. The mixture was stirred for 16 h, then diluted with water, and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with a diluted aqueous solution of sodium carbonate and brine, dried over sodium sulfate and filtered, and the solvent was removed under reduced pressure. The crude product was purified by column chromatography (silica gel, ethyl acetate/methanol gradient). Isoxazole-5-carboxylic acid [2-(2-o-tolyl-chroman-6-yloxy)-thiazol-5-ylmethyl]-amide (112 mg, 59%) was obtained as a white solid., 21169-71-1
