5-IODO-4-METHYL-PYRIDIN-2-YLAMINE Use and Manufacturing
To a stirred solution of 4-methyl-pyridin-2-ylamine (30g, 278mmol, 1 eq) in acetic acid (167ml_) was added periodic acid (12.7g, 55.6mmol, 0.2eq) followed by addition of sulphuric acid (4.8ml_, 90.8mmol, 0.34eq), water (33.3ml_) and iodine (28.7g, 1 1 1 .1 mmol, 0.4eq) at room temperature. Resulting reaction mixture was heated at 80°C for 6 hours. After complete consumption of starting material, reaction mixture was cooled and poured into sodium thiosulfate solution (200ml_), reddish oil was settled down at the bottom. Reaction mixture was decanted from reddish oil and filtrate was basified with 50percent sodium hydroxide solution (100ml_), yellow colored solid was formed. Resulting solid was extracted with diethyl ether (2x200 mL) and dried over sodium sulfate. Organic layer was concentrated under reduced pressure to afford brown semi solid (60g, crude). Crude was purified by column chromatography using silica gel (100-200 mesh). Desired compound was eluted at 15percent EtOAc in hexane to get title compound as faint brown solid (50.7g, 78percent). H NMR (400 MHz, CDCI3)8: 2.27 (s, 3H), 4.46 (bs, 2H), 6.44 (s, 1 H), 8.24 (s, 1 H).
