Versuchsvorschrift

A stirred mixture of [3-(2-Methyl-1,3-dioxolan-2-yl)tricyclo[3.3.1.03,7]non-1-yl]methyl methanesulfonate (2.4 g, 7.5 mmol) [as obtained from preparation 2], K2CO3 (4.5 g, 34.2 mmol), and 1,2,4-triazole (1.5 g, 22.5 mmol) in DMF (30 mL) was heated to 110° C. for 5 h. The reaction mixture was cooled to room temperature, diluted with water, and extracted with ethylacetate. The combined organic layer was washed with brine, dried over Na2SO4, and the solvent was removed under reduced pressure. The crude product was purified by column chromatography to obtain 1-{[3-(2-Methyl-1,3-dioxolan-2-yl)tricyclo[3.3.1.03,7]non-1-yl]methyl}-1H-1,2,4-triazole (1.82 g) as a viscous liquid in 85% yield. m/z (M+1) 290; IR cm−1 2932, 1668, 1506, 1441, 1373, 1311, 1211, 1140, 1047, 876, 753. 1H NMR (CDCl3) 300 MHz δ 7.99 (s, 1H), 7.93 (s, 1H), 4.07 (s, 2H), 4.03-3.92 (m, 4H), 2.42-2.32 (m, 2H), 1.86-1.79 (m, 1H), 1.74-1.65 (m, 2H), 1.52-1.37 (m, 8H), 1.26 (s, 3H).
