4-[(Aminothioxomethyl)amino]benzoic acid Use and Manufacturing

A mixture of 4-(3-benzoylthioureido)benzoic acid (7) (10.0 mmol) and 10percent sodium hydroxide (10.0 mmol) in water (20 mL) was heated under reflux for 30 min. The reaction mixture was cooled and neutralized by HCl. The formed product was filtered off, washed with water, driedand crystallized from butanol to give a white powder in 93percent yield. mp > 300 C;mmax (KBr) 3440, 3339, 3279, 3170, 1684, 1291 cm-1; dH (300 MHz, DMSO-d6) 12.72 (1H, br s, COOH), 9.96 (1H, s, NH), 7.54–7.90 (4H, m, ArH’s), 3.37 (1H, s, NH2); m/z (EI, 70 eV) 196(10), 179(98), 162(98), 134(75), 120(95), 92(35); Elem.Anal.
