実験手順

To a stirring suspension of 3.0 g (0.017 mole) of 1-methyl-4-amino-1-azaspiro[4.5]decane of Example 2 and 5.0 g of NaHCO3 in 50 ml of CHCl3 was added dropwise 3.8 g (0.018 mole) of 3,4-dichlorobenzoyl chloride in 25 ml of CHCl3. The reaction was refluxed for 3 hours, cooled to room temperature, filtered, and the solvent evaporated to give an oil. The residue was triturated with boiling hexane and decanted, the hexane solution afforded 2.6 g of 1-methyl-4-(3,4-dichlorobenzamido)-1-azaspiro[4.5]decane on standing. The solid was dissolved in ether and a solution of ethereal HCl was added. The resulting solid was collected and recrystallized three times from ethanol to give 2.2 g (35%) m.p. 227°-228° C. of 1-methyl-4-(3,4-dichlorobenzamido)-1-azaspiro[4.5]decane hydrochloride.
