Procedure

134 g (0.95 mol) of 4-chlorobenzaldehyde are added to a solution of 15.8 g of 50% strength sodium hydroxide solution in 500 ml of methanol, after which 90 g (0.79 mol) of 4,4-dimethylpentanal are added dropwise at 35° C. in the course of 3 hours. Stirring is carried out for three hours, after which the mixture is neutralized with dilute sulfuric acid and evaporated down and the residue is distilled.
