반응 단계
A solution of triethyloxonium fluoroborate (33.0 g., 0.175 mole) in methylene chloride (75 ml.) was added during 10 minutes to a stirred solution of 2-n-propoxybenzamide (31.3 g., 0.175 mole) in methylene chloride (150 ml.). The solution was stirred for an additional 18 hours at room temperature. The solution was concentrated to about one-fifth volume and was diluted with diethyl ether to precipitate the ethyl 2-n-propoxybenzimidate fluoroborate (44.0 g., 85% yield), m.p. 108°-112°.
