Reaction Steps

To a solution of 5-chloro-3-[(1-piperazinyl)carbonylmethyl]-2-benzothiazolinone (3.0 g) in a mixture of N,N-dimethylformamide (30 ml) and water (5 ml) was added S-methylisothiourea sulfate (4.0 g). The mixture was stirred for 8 hours at 80° C. and then cooled. The precipitates formed were filtered and recrystallized from water (100 ml) to give 5-chloro-3-[(4-amidino-1-piperazinyl)carbonylmethyl]-2-benzothiazolinone hemisulfate (2.63 g).
