Participants

Reaction Steps

To a mixture of 2,4-dichlorophenol (3.20 g) and imidazole (2.67 g) in dimethylformamide (30 ml) was added triisopropylsilyl chloride (3.97 g) in water bath under nitrogen atmosphere, and the mixture was stirred for 3 hours under the same condition. The mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by silica gel column chromatography (n-hexane) to give 1,3-dichloro-4-triisopropylsilyloxybenzene (5.12 g).
