Reaction Steps
Analoguous to Example 4, the reaction is carried out with 3 g of 4.5-dihydro-6-[4-(imidazol-1-yl-methyl)-thien-2-yl]-3(2H)-pyridazinone (prepared analoguous to Example 3, m.p. 178° to 179° C.), 2.9 g of the sodium salt of 3-nitrobenzenesulfonic acid and 2 g of sodium hydroxide in 40 ml of water. The reaction mixture is neutralized by the addition of 2.5 ml of acetic acid.
