Acetic Acid → HCID 68568445, compound

Participants

Reaction Steps

To 16.75 g of 1,3-dichlorobenzene dissolved in 250 ml of THF are added dropwise, at −70° C., 68 ml of a 1.6M solution in hexane of n-butyllithium. After one hour at −70° C., 10 g of 5-chloro-2-nitrobenzaldehyde dissolved in THF are introduced and the mixture is left for 3 hours at this temperature. The resulting mixture is hydrolysed by addition of 5 ml of acetic acid and is allowed to warm to room temperature. The resulting mixture is concentrated and the residue is chromatographed on a column of silica gel, eluting with a 90/10 (v/v) cyclohexane/ethyl acetate mixture to give 7.975 g of the expected product.
