Versuchsvorschrift
A solution of 550 mg of methyl 3-methylsulphonyl-4-(4-BOC-aminopiperidino)benzoate (m.p. 149°-150°) [obtainable by reacting 3-methylsulphonyl-4-chlorobenzoic acid with 4-BOC-aminopiperidine in a melt and subsequently esterifying the product with methyl iodide/K2CO3 in dimethylformamide (DMF)] and 383 mg of guanidine in 6 ml of methanol (abs.) is stirred at 60° for a period of 45 min. After removing the solvent, and after customary working-up, N-diaminomethylene-3-methylsulphonyl-4-(4-BOC-aminopiperidino)benzamide is obtained, m.p. 224°-226°.
