To a solution of 3-(trifluoromethoxy)pyridin-2 -amine (300 mg, 1.68 mmol) in dichloromethane (8 mL) was added N-bromosuccinimide (450 mg, 2.53 mmol) at 20 C. The reaction mixture was stirred at the same temperature for another 5 min and subsequently concentrated to dryness in vacuo. The resulting residue was purified by column chromatography (silica gel, 100-200 mesh, 15% ethyl acetate in petroleum ether) affording product (220 mg, 51 %): NMR (400 MHz, DMSO- ) delta 8.03 (d, J = 2.0 Hz, 1H), 7.75 – 7.74 (m, 1H), 6.68 (brs, 2H).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 1206981-49-8, 3-(Trifluoromethoxy)pyridin-2-amine, other downstream synthetic routes, hurry up and to see.
