实验步骤: A solution containing (buta-1,3-dien-2-yloxy)(trimethyl)silane (12.5 ml, 70.7 mmol) in toluene (50 ml), was treated with (methylsulfonyl)ethene (4.1 ml, 47.1 mmol) and heated under reflux for 76 hours. After which time, the reaction mixture was cooled to room temperature and concentrated in-vacuo to give a yellow oil. The oil was dissolved in CH2Cl2 (120 ml) and filtered through Celite®. The filtrate was concentrated in-vacuo and the resulting residue was then dissolved in MeOH (8 ml) with cooling (ice/water). It was then treated with TFA (2.0 ml). The reaction mixture was stirred at 0° C. for a further 10 minutes and then at room temperature for 25 hours. The reaction mixture was concentrated in-vacuo and the residue was purified by flash column chromatography (0-10% MeOH/CH2Cl2) 100 g SNAP cartridge on the Biotage Isolera to give the title compound 1.2 g (14%) as a thick yellow oil.

The vessel was closed and heated for 50 hours at 100° C. Methanol was evaporated and the residue was re-dissolved in dichloromethane, washed with a saturated NaHCO3 solution, dried over MgSO4, filtered and evaporated. The residue was further purified by means of column chromatography. 7-(pyridin-3-ylmethyl)-7-aza-bicyclo[2.2.1]heptane-1-carbonitrile (structural formula below) was thus obtained in a 69% yield and characterised by proton (1H-NMR) and carbon (13C-NMR) nuclear magnetic resonance, infrared (IR) spectrophotometry and mass spectrum (MSES) as follows.

实验步骤: This synthesis was performed according to scheme 2, with details as follows. In a dry, pressure resistant vessel of 20 ml, 1.25 g (6.5 mmole) 4-methanesulfonylcyclohexanone 9, 0.89 g (6.5 mmole) 4-methoxybenzylamine, 1.11 g (13 mmole) acetone cyanohydrine and 1.32 g (13 mmole) triethylamine were dissolved in 16 ml dry methanol. The vessel was closed and heated to 100° C. for 50 hours. Methanol was evaporated and the residue was redissolved in dichloromethane. The solution was washed with a saturated NaHCO3 solution and dried over MgSO4. After filtration of the solids, the volatile components were evaporated. 7-(4-methoxybenzyl)-7-azabicyclo[2.2.1]heptane-1-carbonitrile 6a was obtained as a brown oil in a 97% yield and characterised by proton (1H-NMR) and carbon (13C-NMR) nuclear magnetic resonance, and mass spectrum (MSES) as follows: The vessel was closed Methanol was evaporated the residue was redissolved in dichloromethane The solution was washed with a saturated NaHCO3 solution dried over MgSO4 After filtration of the solids the volatile components were evaporated
