Methyl 2-amino-5-iodobenzoate (17.8 g, 64 mmol) was heated in 300 mL of formamide at 190° C. for 2 hours. The mixture was cooled to room temperature and the solid product was filtrated and dried in vacuum. The formed product 1403-174 was used without further purification. (10 g, 56.1%): LC-MS: 273 [M+1]+, 1H NMR (DMSO-d6): δ 7.46 (d, J=9.0 Hz, 1H), 8.10 (m, 2H), 8.36 (d, J=2.1 Hz, 1 H), 12.40 (s, 1H).
