実験手順

2-(2,4-Difluorophenylsulfanyl)-1-nitrobenzene (1.04 g, 78%) was prepared from 2,4-difluorothiophenol (0.73 g, 5.5 mmol) and 2-fluoronitrobenzene (0.71 g, 5.0 mmol) following the general procedure A. This compound was reduced to 2-(2,4-difluorophenylsulfanyl)aniline (0.64 g, 70%) following the general procedure B. 1-[2-(2,4-Difluorophenylsulfanyl)phenyl]-3-(thiazol-2-yl)urea (130 g, 72%) was prepared from 2-(2,4-difluorophenylsulfanyl)aniline (118 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
