Procedure

To a solution of ethyl N-[2-amino-6-({[(2,4-dichlorophenyl)amino]carbonothioyl}amino)phenyl]-beta-alaninate (Reference Example 26; 174 mg, 0.407 mmol) in tetrahydrofuran (4 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (234 mg, 1.22 mmol) at room temperature. The resultant mixture was stirred at 50° C. for 2 hr. The reaction mixture was diluted with ethyl acetate, washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with ethyl acetate to give the title compound as an oil (122 mg, 0.309 mmol, 76%).
