Participants

Reaction Steps

A mixture of 4.0 g of 2-[[[(1-methyl-2-(4-(1-{4-chlorophenyl}-ethoxy)-phenyl)-2-E-[ethoxyimino]ethylidene)amino]oxy]methyl]-α-(methoxyimino)-phenylacetic acid methyl ester and 5.3 ml of a 8M solution of methylamine in ethanol is left to stand at room temperature for 4 days. The mixture is then concentrated by evaporation in vacuo. The residue is taken up with methyl acetate; the solution is washed with water and saturated sodium chloride solution, dried over sodium sulfate and concentrated by evaporation in vacuo. The residue is recrystallised from methyl acetate/hexane 1:1 to yield the title compound having a melting point of 81-83° C. (compound 3-4.2).
