Versuchsvorschrift

To a solution of 1-(phenylcarbamoyl)cyclopropanecarboxylic acid (214 mg, 1.04 mmol) in tetrahydrofuran (2 mL) were added oxalyl chloride (178 μL, 2.08 μmol) and N,N-dimethylformamide (2 drops) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. The solvent was evaporated under reduced pressure. To a solution of the obtained residue in N,N-dimethylacetamide (5 mL) was added N-[6-(4-amino-2-fluorophenoxy)-1,3-benzothiazol-2-yl]cyclopropanecarboxamide (275 mg, 0.80 mmol), and the mixture was stirred at room temperature for 18 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=80/20→20/80, NH silica gel, hexane/ethyl acetate=50/50→0/100) and recrystallized from ethyl acetate to give the title compound (241 mg, 57%) as white crystals.
