Versuchsvorschrift

6′-Bromo-4-methoxyspiro[cyclohexane-1,2′-inden]-1′(3′H)-imine (Example 19 Step 2, 1.41 g, 4.57 mmol) and 2-oxopropanethioamide (Intermediate 2, 1.42 g, 13.7 mmol) were dissolved in dry MeOH (30 mL) and the resulting solution was heated at 60° C. under an atmosphere of nitrogen. After 15 h the reaction was allowed to cool to r.t. A precipitate had formed which was filtered off and dried in vacuo, yielding the title compound (1.16 g, 64% yield) as a mixture of isomers. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.18 (m, 4 H), 1.47 (m, 2 H), 1.87 (m, 2 H), 2.27 (m, 3 H), 3.03 (m, 3 H), 3.20 (s, 3 H), 6.98 (d, 1 H), 7.34 (d, 1 H), 7.51 (dd, 1 H); MS (APCI+) m/z 394 [M+H]+.
