Reaction Steps

The product from Example 38, Part B (150 mg, 0.46 mmol) was treated with sodium hydride (17 mg, 0.55 mmol, 80%) and ethyl iodide (55 ml, 0.69 mmol) in dry dimethylformamide (3 ml) and stirred at room temperature for 48 h. The reaction was diluted with 50 ml water, and extracted with 4-30 ml methylene chloride. The combined organic extracts were dried over anydrous magnesium sulfate, filtered, and concentrated in vacuo to dryness. Chromatography on silica gel (50 g, 1/1 hexanes/ethyl acetate) afforded the desired product, 144 mg (88%) as a clear viscous oil. CI-HRMS calcd. for C19H27N6O1 (M+H): 355.2246. Found: 355.2240.
