Reaction Steps

Clomiphene (6.06 g, 14.9 mmol) was dissolved in tetrahydrofuran (100 ml) and cooled to -40° C. t-Butyl lithium (1 M in pentane, 24 mmol) was added slowly. After 5 minutes, ethylene oxide (14.6 ml, 290 mmol) was added, and the reaction mixture was stirred for 6 hours, poured into water and extracted with ether. The ether layer was evaporated and chromatographed on a silica gel column using 1:1:0.1 ether/petroleum ether/triethylamine as eluant to yield trans product (1.96 g, 27.1%, oil): and cis product (1.56 g, 21.5%, oil): Assignment of 1HNMR for aliphatic protons are presented in Table 2.
