Hexachloroethane → HCID 68936932, compound

Participants

Reaction Steps

As in Example 553 (above), using 3-(7-chloro-9,10-dihydro-1-thia-benzo[f]azulen-4-ylidenemethyl)-phenylamine, n-BuLi in hexanes, THF, and hexachloroethane. Purify the crude residue by column chromatography (5% to 20% to 30% EtOAc:hexanes) to give title compound as an oil (21%) along with recovered starting material: 1H NMR (CDCl3, 400 MHz) δ 2.06-3.02 (m, 4 H), 3.53 (br s, 2 H), 6.32 (s, 1 H), 6.38 (d, J=7.2 Hz, 1 H), 6.48 (dd, J=7.2 Hz, 1.6 Hz, 1 H), 6.79 (s, 1 H), 6.93-6.96 (m, 3 H), 7.02 (dd, J=8.2 Hz, 2.2 Hz, 1 H), 7.27 (d, J=8.2 Hz, 1 H). TLC Rf=0.55 (30% EtOAc:hexanes).
