Reaction Steps
700 mg of N-diaminomethylene-2-methyl-4-(1-cyclopenten-3-yl)-5-methylsulfonylbenzamide [which can be prepared according to Example 1; m.p. 212°-214°] are dissolved in 20 ml of acetone, and 6.1 ml of methanesulfonic acid are added, while stirring. Filtration and lyophilization give N-diaminomethylene-2-methyl-4-(1-cyclopenten-3-yl)-5-methylsulfonylbenzamide, methane-sulfonate, m.p. 202°-204°.
