3-Bromophenol → HCID 19744768, compound

Participants

Reaction Steps

1.4 g of 3-bromomethylbenzaldehyde was dissolved in 3 ml of dimethylformamide, and the solution was added to 5 ml of a tetrahydrofuran solution of phenolate, prepared from 1.5 g of 3-bromophenol and 0.36 g of 60% oily sodium hydride. The mixture was stirred for 2 hours at room temperature. The solvent was evaporated, and water and ethyl acetate were added to the residue to extract it. The extract was worked up in a customary manner to give crude 3-(3-bromophenoxymethyl)benzaldehyde. When the same reaction as in Referential Example 12 was performed using 440 mg of the resulting aldehyde compound, 747 mg of tributyl(3-thienyl)stannane and 10 mg of tetrakis(triphenylphosphine)palladium, 341 mg (yield 77%) of 3-[3-(3-thienyl)phenoxymethyl)benzaldehyde was obtained.
