実験手順

A solution of 8-aza-spiro[4.5]decane hydrochloride (791 mg, 4.50 mmol) and triethylamine (2.24 mL, 16.1 mmol) in 20 mL of anhydrous dimethylformamide was added under nitrogen dropwise to a solution of the carbonate prepared in Example 5 (2.00 g, 3.22 mmol) in 25 mL of anhydrous dimethylformamide. After the addition the reaction was stirred at room temperature overnight. The reaction was diluted with ethyl acetate, extracted one time with 1N HCl, multiple times with saturated Na2CO3 and then water, dried (MgSO4) and the solvent removed under reduced pressure to give 1.65 g of an oil. Purification of the oil on silica gel (230-400 mesh) using 20% ethyl acetate-methylene chloride as the eluent gave 1.01 g (52%) of the title compound as a light yellow oil, MS [M+H]+ 622.
