Versuchsvorschrift

A mixture of the bromide (58) (60.0 mg, 0.124 mmol) prepared as described in example 172 and lithium thiomercaptide (13 mg, 0.2481 mmol) in p-dioxane (5 mL) was refluxed for 16 h. A further 10 mg of LiSMe was added and refluxing was continued for a further 9 h. The mixture was diluted with water, extracted with ethyl acetate. The organic layer was dried, the drying agent was removed and the solution was concentrated to drynessto give the sulfide (130 directly (47.1 mg, 84%) which crystallised from ethyl acetate/petroleum ether as an orange powder, mp 218–220° C. 1H NMR δ [(CD3)2SO] 11.07 (br s, 1H), 9.39 (br s, 1H), 8.39 (d, J=2.4 Hz, 1H), 7.80 (s, 1H), 7.61–7.56 (m, 2H), 7.53–7.43 (m, 3H), 7.15 (dd, J=8.8, 2.4 Hz, 1H), 4.52 (t, J=6.9 Hz, 2H), 2.45 (t, J=7.0 Hz, 2H), 2.01 (m, 2H), 2.00 (s, 3H).
