Pyridine → 3,5-Dichloro-4-(3-(n-(4-chlorophenyl)carbamoyloxy)propyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene

Participants

Reaction Steps

A solution of 0.17 g of 3,5-dichloro-4-(3-hydroxypropyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene, 0.09 g of 4-chlorophenyl isocyanate and a catalytic amount of pyridine dissolved in 10 ml of toluene was heated at 60° to 70° C., while stirring, for 3 hours, and the reaction mixture was then concentrated to give a residue. The residue was subjected to silica gel chromatography, which afforded 0.19 g of 3,5-dichloro-4-(3-(N-(4-chlorophenyl)carbamoyloxy)propyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene (77% yield), m.p., 54.3° C.
