Phenethyl isocyanate → methyl (Z)-3-[2-butoxy-3'-(1-methyl-3-phenethylureido)biphenyl-4-yl]-2-ethoxyacrylate

Participants

Reaction Steps

40 mg (0.1 mmol) of methyl (Z)-3-(2-butoxy-3′-methylaminobiphenyl-4-yl)-2-ethoxyacrylate and 16 mg (0.11 mmol) phenethyl isocyanate are heated at 85° C. by microwave in an Emrys Optimizer machine for 20 minutes. The residue obtained is purified by chromatography on a column of silica eluted with a 95/5 and then 90/10 heptane/ethyl acetate mixture. 40 mg (72%) of methyl (Z)-3-[2-butoxy-3′-(1-methyl-3-phenethylureido)biphenyl-4-yl]-2-ethoxyacrylate are obtained.
