Participants

Reaction Steps

A solution of N-{3-[(2-amino-1,3-benzothiazol-6-yl)oxy]-4-methoxyphenyl}-3-(1-cyanocyclopropyl)benzamide (91 mg, 0.20 mmol), cyclopropanecarbonyl chloride (105 mg, 1.00 mmol) and N,N-dimethylpyridine-4-amine (122 mg, 1.00 mmol) in pyridine (2 mL) was stirred at room temperature for 18 hr. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (eluent:hexane/ethyl acetate=1:1), and triturated with diethyl ether to give the title compound (58 mg, 55%) as a pale-yellow solid.
