Sodium ethoxide → (E)-(4-Chlorophenyl)(cyclopropyl)methanone O-((2-methyl[biphenyl]-3-yl)methyl)oxime

Participants

Reaction Steps

In a manner similar to General Procedure F of European Patent Publication No. 4,754, published Oct. 17, 1979, 1.96 g (0.01 mole) of (E)-(4-chlorophenyl)(cyclopropyl)methanone oxime was treated with 0.23 g (0.01 mole) of sodium ethoxide in 10 ml of ethanol, and the mixture was evaporated to dryness. The residue was dissolved in a minimum amount of solvent consisting of N,N-dimethylformamide and t-butanol (9:1 ratio) and treated with 2.16 g (0.01 mole) of 3-chloromethyl-2-methyl[1,1'-biphenyl] to yield, after purification by column chromatography, 0.83 g of (E)-(4-chlorophenyl)(cyclopropyl)methanone O-[(2-methyl[1,1'-biphenyl]-3-yl)methyl]oxime as an oil.
