実験手順
310 cm3 of ethanol saturated with ammonia was added to 83 g (0.41 mol) of 4-fluorobenzimidate hydrogen chloride and stirred at room temperature for one day and night. Approximately half of the ethanol was distilled off and the residue was recrystallized to yield 70 g (0.40 mol) of 4-fluorobenzamidine hydrogen chloride.
