| Reactant | Sec butyloxycarbonyl methylene triphenylphosphorane | HCID 13076692 | — |
| Reactant | 4-(4-(Trifluoromethyl)phenoxy)benzaldehyde | HCID 13300844 | — |
| Solvent | Dichloromethane | HCID 6344 | — |
| Product | Sec butyl 4-(p-trifluoromethylphenoxy)cinnamate | HCID 86740131 | 97.4% |
Reaction Steps
A mixture of 4(p-trifluoromethylphenoxy)benzaldehyde (30 g) and sec butyloxycarbonyl methylene triphenylphosphorane (50 g) dissolved in dichloromethane was allowed to stand for 1 hour at room temperature. After evaporation of the solvent the white solid was tritiated with petroleum ether to give a solution which on evaporation yielded sec butyl 4-(p-trifluoromethylphenoxy)cinnamate (40 g) b.p. 150°/0.007 mm.
