Versuchsvorschrift

The title compound 2-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)-5-(4-methoxyphenyl)thiazole-4-carboxylic acid (1) was prepared by the following procedure: To 5-(4-methoxyphenyl)-2-(1,2,3,4-tetrahydroquinolin-7-yl)thiazole-4-carboxylic acid (1L) (0.070 g, 0.19 mmol) and N-(benzo[d]thiazol-2-yl)-1H-imidazole-1-carboxamide (1M) (0.051 g, 0.21 mmol) was added DMF (2 mL). The reaction mixture was allowed to stir at rt overnight. To the reaction mixture was added EtOAc and water. The layers were separated and the aqueous layer was extracted with EtOAc. The combined organic extracts were washed sequentially with water, brine, dried over MgSO4, filtered, and concentrated under reduced pressure. The crude residue was purified by reverse phase HPLC to provide 0.028 g (27%) of the desired product 2-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)-5-(4-methoxyphenyl)thiazole-4-carboxylic acid (1): LC/MS (APCI): m/z 543.1 (M+H).
