Reaction Steps
A solution of 4-amino-5-chloro-2-methoxy benzoic acid (0.6 g) and N,N'-carbonyldiimidazole (0.49 g) in anhydrous dimethylformamide (DMF) (15 ml) was stirred at room temperature for 30 minutes, then a solution of N-nitro-N'-aminoethylguanidine hydrochloride (0.55 g) and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in DMF was added. The mixture was stirred for 4 hours at 50° C., then was cooled, poured into water and extracted with methylene chloride. The organic layer was washed with sodium carbonate solution and dried. After cooling, the title compound was collected as a solid, M.p. 226°-227° C. (dec.)
