Procedure

Sodium hydride (55%, 0.17 g, 4.0 mmol) was added in a single portion to a solution of (4,6-dichloropyrimidin-5-yl)amine (0.61 g, 3.72 mmol) and ethyl iodide (0.30 mL, 3.8 mmol) in dry DMF (3 mL) at room temperature. The suspension was stirred for 18 hours, then diluted with saturated aqueous ammonium chloride (5 mL) and water (20 mL). The mixture was extracted with diethyl ether (30 mL), and the extract was dried, filtered and concentrated. Flash column chromatography on silica, eluting with 10% ethyl actetate—hexanes, gave ethyl(4,6-dichloropyrimidin-5-yl)amine (0.321 g, 1.67 mmol, 45%). LC-MS (LCT2) m/z 192, 194 [M+H+], Rt 6.07 min.
