YieldReaction ConditionsOperation in experiment
65% Step 26-amino-5-iodonicotinic acidA solution of methyl 6-amino-5-iodonicotinate (723 mg, 2.6 mmol) and potassium hydroxide (729 mg, 13.0 mmol) in 40 mL methanol/H2O (3: 1 ratio) was heated at 50 0C. After 4 hours 10 mL THF was added and the reaction continued until 22 hours. The reaction was cooled to room temperature and concentrated HCl added until the solution was pH 4. The solution was concentrated to a volume of 15mL and the resulting precipitate filtered, rinsed with H2O and 40% EtOAc/hexane to give the title compound as a white solid (443mg, 65%).
1.77 g With water; potassium hydroxide; In tetrahydrofuran; at 50℃; for 48h; Preparation 4 6-Amino-5-iodonicotinic acid A mixture of methyl 6-amino-5-iodonicotinate, (2.78 g, 10 mmol, 1 eq) and potassium hydroxide (2.8 g, 5 eq) in THF/H2O (120 mL, 3:1) was heated at 50 C. for 48 hours. The reaction was then cooled to room temperature and concentrated HCl was drop wise added until a pH around 3-4 was achieved. The solution was concentrated and the resulting precipitate was collected by filtration to give the title compound as a slightly brown solid (1.77 g.) 1H NMR (DMSO-d6) δ: 12.64 (br. s., 1H), 8.47 (d, J=2.1 Hz, 1H), 8.25 (d, J=1.8 Hz, 1H), 6.88 (br. s., 2H)
