Participants

Reaction Steps

A mixture of 10.2 g (0.040 ) of crude 2-(4-fluorophenyl)-2-[1-(4-fluorophenyl)ethenyl]oxirane and 7.0 g (0.065 mol) of potassium triazole in 60 mL of DMF was heated at 60° overnight, then cooled and poured into 100 mL of 1:1 Et2O/hexanes. After washing the organic layer three times with H2O and once with brine, a precipitate formed in the organic layer. Filtering gave 4.8 g of a brown solid which was recrystallized from 500 mL of cyclohexane to yield 2.5 g of a light-tan powder, mp 136°-137° C.: NMR (CDCl3)δ1.7 (br s, OH); 4.7 (q, 2H); 5.3 (s, 1H); 5.5 (s, 1H); 6.8-7.1 (m, 6H); 7.4 (m, 2H); 7.8 (s, 1H); 7.9 (s, 1H); IR (nujol) 3120 (br), 1900, 1600, 1505, 1220, 1139, 835 cm-1.
