Procedure
A mixture of 1,6-dibromohexane (9 ml), 50% w/v sodium hydroxide (40 ml), 2-(2-naphthalenyl)thioethanol (4 g), TAB (0.8 g) and hexane (30 ml) was stirred vigorously at 20°, under nitrogen for 4 h. Water (100 ml) and ether (100 ml) were added and the mixture was further extracted with ether (100, 2×50 ml). The combined, dried ether extracts were evaporated in vacuo to give a yellow oil. Purification by FCC eluting with light petroleum (b.p. 60°-80°):ether (30:1→1:1) gave the title compound as a white crystalline solid (5.7 g), m.p. 38°-40° (softens 36°).
