2,4-Dichlorophenol → HCID 13849851, compound

Participants

Reaction Steps

50 g (0.28 mole) of 1-chloro-3-ethyl-3-methyl-pentan-2-one, dissolved in 30 ml of N,N-dimethylformamide, are added to a mixture of 38.6 g (0.28 mole) of potassium carbonate and 45.6 g (0.28 mole) of 2,4-dichlorophenol in 200 ml of N,N-dimethylformamide at the boiling point. The mixture is heated at the boiling point for 10 hours, cooled to room temperature and filtered and the solvent is distilled off under reduced pressure. Distillation of the residue gives 75.7 g (93.5% of theory) of 1-(2,4-dichlorophenoxy)-3-ethyl-3-methyl-pentan-2-one as a color less liquid of boiling point 141°-144° C./0.15 mm. ##STR64##
