Procedure
(6-Chloro-5-cyclopropylpyridazin-3-yl)hydrazine trifluoroacetic acid salt (W3.012; 400 mg) was converted and worked up analogously to W2.008, except that, instead of 0.5, one further equivalent of cyanogen bromide solution was added. 260 mg of the title compound were obtained in sufficient purity.
