Sodium hydride → HCID 90200802, compound

Participants

Reaction Steps

A solution of Example 74d (0.41 g, 1.6 mmol) in dimethylformamide (15 mL) was treated with 60% sodium hydride (0.096 g, 2.4 mmol) at room temperature. The reaction mixture was stirred for 30 min, and then was treated with (2-(chloromethoxy)ethyl)trimethylsilane (0.40 g, 2.4 mmol). The reaction mixture was then stirred for 2 hours. It was partitioned between ethyl acetate and water. The aqueous layer was extracted with additional ethyl acetate twice. The combined organic layers were washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by flash chromatography on silica gel, eluting with 20% ethyl acetate to afford 0.50 g (81%) of the title compound.
