実験手順

A mixture of 5-chlorothiazol-2-amine hydrochloride (513 mg, 3 mmol), 5-chloro-2-methoxybenzoic acid (670 mg, 3.6 mmol), 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide hydrochloride (1.15 g, 6 mmol), 1-hydroxybenzotriazole hydrate (810 mg, 6 mmol) and 4-(dimethylamino)pyridine (73 mg, 0.6 mmol) in pyridine was stirred at room temperature for 2 hours. The volatiles were removed under vacuum, and the resulting mixture was diluted with water and extracted with ethyl acetate. The organic extract was dried (Na2SO4), filtered and concentrated. The residue was washed with a small amount of ethyl acetate, and filtered to afford the title compound. MS (ESI) m/z 303 (M+H)+.
