Participants

Reaction Steps

10 parts by weight of 2-butyryl-5-(2-oxoquinol-3-yl)-cyclohexane-1,3-dione, 2.0 parts by weight of ethoxyamine and 100 parts of methanol were stirred for 8 hours at room temperature. The solvent was distilled off under reduced pressure, the residue was taken up in 200 parts of dichloromethane, and the solution was washed with 5% strength hydrochloric acid, dried over sodium sulfate and evaporated down under reduced pressure. 2-(1-Ethoxyaminobutylidene)-5-(2-oxoquinol-3-yl)-cyclohexane-1,3-dione of melting point 155°-157° C. was obtained (active ingredient No. 2).
