4-Fluorophenyl isocyanate → N1-[5-({7-[3-(Dimethylamino)propoxy]-6-methoxy-4-quinolyl}sulfanyl)-2-thienyl]-N'-(4-fluorophenyl)urea

Participants

Reaction Steps

5-({7-[3-(Dimethylamino)propoxy]-6-methoxy-4-quinolyl}sulfanyl)-2-thiophenylamine (190 mg), para-fluorophenyl isocyanate (69 mg) and tetrahydrofuran (30 ml) were stirred together at room temperature for 30 minutes. The organic solvent was distilled off under reduced pressure, and the residue was purified by column chromatography (ethyl acetate, followed by ethyl acetate:methanol=10:1) using NH type silica gel. The solvent was distilled off under reduced pressure, and ethyl acetate was added to the residue for solidification to obtain 16 mg of a yellowish-brown solid.
