実験手順
To a solution of 18.2 g of N-(2-methyl-4-chlorophenyl)-N'-methylformamidine in 60 ml of abs. dioxane are added dropwise at room temperature 15.1 g of N-ethoxymethylenemethanesulphonamide and the solution is stirred for 1 hour at 60° C. The reaction mixture is subsequently concentrated and the crystallised product is recrystallised from toluene, affording the compound of the formula ##STR4## as a white powder with a melting point of 142°-143° C. The following compounds are also prepared in analogous manner: ##STR5##
