実験手順

A mixture of 1-(2-pyrimidinyl)piperazine (16.4 g., 0.1 mole), 1,4-dichlorobutane (23.8 g., 0.19 mole), sodium carbonate monohydrate (30.8 g., 0.25 mole) and potassium bromide (44.6 g., 0.375 mole) in 150 ml. of isopropanol is stirred and refluxed for an 8-hr. period. The hot reaction mixture is filtered and insolubles washed with hot isopropanol. Concentration of the combined filtrates under reduced pressure and trituration of residual material with acetone provides 8-(2-pyrimidinyl)-8-aza-5-azoniaspiro[4.5]decane bromide in yields of 50-90%.
