実験手順

To a solution of 2-amino-5-iodopyridine (1.00 g; 4.55 mmol) in 10 mL of DMF was added 545 mg of 60% NaH (13.6 mmol) and 0.85 mL of iodomethane (13.6 mmol). The mixture was stirred for 14 h, and the mixture was neutralized with 1M HOAc. The mixture was extracted with Et2O, the extract was washed with water and brine, dried with MgSO4, filtered, and concentrated. Chromatography (0-25% EtOAc in hexanes) provided 700 mg (2.82 mmol) of (5-iodo-pyridin-2-yl)-dimethyl-amine.
