Reaction Conditions:

in diethyl ether at 20;Reflux;

Steps:

1

To a solution of 1-cyclopropylethan-1-one (1.0 g, 11.2 mmol) in anhydrous Et₂O (5 mL) was added a solution of MgMeBr (4.4 mL, 13.2 mmol) at a rate suitable to maintain gentle reflux of the solvent, to afford the expected alcoholate as a white precipitate. The reaction mixture was maintained refluxing for an additional 30 minutes, then stirred at RT overnight, and quenched with sat. NH₄Cl solution (5 mL). The resulting mixture was extracted with Et₂O (5 mL), and the combined organic layers were washed with brine (5 mL), dried over Na₂SO₄, and filtered. The filtrate was concentrated in vacuo to afford 2-cyclopropylpropan-2-ol as a pale yellow oil (1.1 g, 92%). ¹H NMR (500 MHz, CDCl₃) δ 1.18 (s, 6H), 0.97-0.94 (m, 1H), 0.39-0.30 (m, 4H).
