Through careful choice of reaction conditions, alkylation of estradiol with chloromethyl methyl ether may yield either the 3,17β-bis(methoxymethyl) ether or the 3-methoxymethyl ether derivative.Treatment of either of these protected estradiols with s-butyllithium, then with trimethylsilyl chloride affords, regioselectively, the 2-trimethylsilyl derivatives which can conveniently be converted into 2-bromo- or 2-iodo-estradiol.
