Procedure

To a solution of 0.9 g of bis[chloro-(2,6-difluorobenzylidene)]hydrazine [prepared in the preceeding step b.)] in 18 ml of tetrahydrofuran of 40° C. temperature, 0.59 ml of hydrazine hydrate is dropped during 1 minute. After filtering, the precipitate is washed with water and dried to give 0.5 g of desired product as yellow crystals.
