Procedure
A mixture of N-{3-amino-2-[(2,3-dihydroxypropyl)amino]phenyl}-N′-(2,4-dichlorophenyl)thiourea (Reference Example 86; 1.71 g, 4.25 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.44 g, 12.8 mmol) in tetrahydrofuran (43 mL) was stirred at 50° C. for 30 min. 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 (687 mg, 1.87 mmol, 44%) as a colorless amorphous.
