実験手順

As described for example 1a) (4-chloro-2-cyano-phenyl)-carbamic acid ethyl ester (71.0 g, 316 mmol) using methoxymethyl-carboxylic acid hydrazide instead of cyclopropane-carboxylic acid hydrazide, was converted to the title compound (73.9 g, 88%) which was obtained as a yellow solid. MS: m/e=264.9 [M+H]+.
