Reaction Steps

2-(2-Methoxycarbonylphenylsulfanyl)nitrobenzene (1.15 g, 80%) was prepared from methyl thiosalicylate (0.92 g, 5.5 mmol) and 2-fluoronitrobenzene (0.71 g, 5.0 mmol) following the general procedure A. This compound was reduced to 2-(2-methoxycarbonyl-phenylsulfanyl)aniline (0.75 g, 73%) following the general procedure B. N-[2-(2-Methoxycarbonylphenylsulfanyl)phenyl]-N′-(thiazol-2-yl)urea (142 mg, 74%) was prepared from 2-(2-methoxycarbonylphenylsulfanyl)aniline (130 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
