Procedure
To a stirring solution of 0.86 g (6.0 mmol) of isoquinolin-3-ylamine in dry THF (30 mL) was added 1.25 g (7.0 mmol) of di-imidazol-1-yl-methanethione. The reaction mixture was refluxed for 30 min. After cooling to room temperature, a solution of 1.7 g (10 mmol) of 2,3-diamino-benzoic acid methyl ester (for synthesis see example 1) in THF (40 mL) and DIEA (2 mL) was added subsequently. The reaction mixture was stirred at room temperature for 1 h and diluted with hexanes (40 mL). The resulting precipitate was filtered. The solid was washed with water and ether and dried under vacuum to give 2-amino-3-(3-isoquinolin-3-yl-thioureido)-benzoic acid methyl ester as a solid.
