Reaction Steps

A solution of 2-aminopyridine (9.4 g.) in dried toluene (25 ml.) was dropwise added at 100° C to a suspension of 55% sodium hydride (5.04 g.) in dried toluene (10 ml.). The mixture was stirred for 2 hours at 100° C. To the solution were added bromoacetaldehyde diethyl acetal (26 g.) and dried toluene (5 ml.). The mixture was stirred for 19 hours at 115° C and cooled to ambient temperature. The reaction mixture was post-treated according to similar manners to those of the above-mentioned Examples to give oil of 2-pyridylaminoacetaldehyde diethyl acetal (8 g.).
