実験手順

13.2 g (35.7 mmol) of N-[2-chloro-3-(1-piperidinyl)propoxy]-3-pyridinecarboximidamide dihydrochloride was added to a solution of 16.5 g (143.5 mmole) of potassium tert-butoxide dissolved in 150 ml of tert-butanol. The mixture was boiled for 6 hours, then evaporated in vacuum. 100 ml of 5% sodium hydroxide solution was added and the mixture was extracted three times with 300 ml portions of ethyl acetate.
