Versuchsvorschrift

Paraiodophenol (25 g) was dissolved in DMF (100 ml), followed by the addition of potassium t-butoxide (25 g) and methoxymethyl chloride (13 ml), and the mixture was reacted at 60° C. overnight. The reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed with water and brine, dried and evaporated. The resulting residue was subjected to a silica gel short column, to give 4-methoxymethoxy-1-iodobenzene as an oil (26.5 g, yield; 88%).
