90% | With hydrogen iodide; In water; acetonitrile; at 70℃; for 20.0h; | 4-Chloro-2,6-dimethyl-3-nitro-pyridine (1.1054 g, 5.9239 mmol), acetonitrile (4.0 mL), and aqueous hydroiodic acid (concentrated, 57percent, 4.0 mL) were combined and heated to 70 °C for 20 h. The mixture was partitioned between CH2CI2, aqueous sat'd Na2C03, and aqueous NaOH (1 M). The aqueous layer was extracted with CH2CI2. The combined organic phases were dried over Na2S04, filtered and concentrated. The residue was chromatographed on silica gel, eluting with 0- 100percent EtOAc in hexanes to yield 4-iodo-2,6-dimethyl-3-nitro-pyridine (1.48 g, 90percent). MS m/z 279. 1 [M+H]+ |

In ethanol; dichloromethane; | (c) 4-(4-Cyanophenyl)amino-2,6-dimethyl-3-nitropyridine A solution of <strong>[15513-48-1]4-chloro-2,6-dimethyl-3-nitropyridine</strong> (9.80 g, 52.5 mmol) and 4-aminobenzonitrile (6.20 g, 52.5 mmol) in ethanol (160 ml) was stirred at room temperature for 16 hours. The solvent was removed under reduced pressure and the residue was dissolved in dichloromethane (200 ml), and washed with saturated aqueous sodium bicarbonate (100 ml). The organic phase was dried (MgSO4) and concentrated under reduced pressure to give a gum which was crystallized by adding ether (100 ml) and sonicating for 5 minutes. | |
