실험 절차
(iv)a) 2,2-Di-(hydroxymethyl)-butanethiol (0.5 g.), trimethyl 4-bromo-orthobenzoate 2 (1.0 g.) and triethylamine (0.1 ml.) were heated at 130°, under a current of nitrogen, for 45 minutes. The volatile components were removed in vacuo (2.00 mm.), at 140°. The residue was purified by chromatography on alumina (alumina Woelm TSC) eluting with 1:6 dichloromethane: hexane, saturated with ammonia. 1-(4-Bromophenyl)-4-ethyl-2,6-dioxa-7-thiabicyclo[2,2,2]octane was obtained as colourless crystals (80 mg.).
