実験手順

1-Fluorocyclopropanecarboxylic acid (crude) (0.84 g, 0.0081 moles) was added in two portions to a solution of methylene chloride (50 ml ) and carbonyl di-imidazole (1.31 g, 0.0081 moles). The reaction was allowed to stand for 1 hour and then 5-amino-2-methoxypyridine (0.83 ml , 0.0081 moles) was added to it in one portion. The reaction mixture was allowed to stand at room temperature for 1 hour. The reaction mixture was then washed with saturated sodium bicarbonate (50 ml ), 5% hydrochloric acid (20 ml ) and saturated sodium bicarbonate solution (25 ml ); dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to give 0.5 g of crude N-(2-methoxy-5-pyridyl)-1-fluorocyclopropanecarboxamide.
