The reaction was stirred at 0° C. for 1 h. The crude reaction was subsequently diluted with H2O. A filtration and washing (H2O) of the precipitate provided the desired product as a beige solid (195 mg, 52%). The product used without further purification. 1H NMR (400 MHz, CD3OD) δ ppm 8.16 (br. s., 1H), 7.99 (m., 1H), 7.77 (br. s., 1H), 7.46-7.67 (m, 2H), 1.45-1.68 (m, 1H), 0.46-0.90 (m, 4H); MS ESI 425.0 [M+H]+, calcd for [C15H13IN4OS+H]+ 425.0.
