Participants

Reaction Steps

To a solution of N-{3-amino-2-[(5-hydroxypentyl)amino]phenyl}-N′-(2,4-dichlorophenyl)thiourea (Reference Example 111; 554 mg, 1.34 mmol) in tetrahydrofuran (15 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (771 mg, 4.02 mmol) at room temperature. The resultant mixture was stirred at 40° C. for 2.5 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 flash column chromatography on silica gel eluting with a 30-90% ethyl acetate/n-hexane gradient mixture to give the title compound as an oil (308 mg, 0.813 mmol, 61%).
