PROCEDURE
实验过程
Lithium aluminum hydride in diethyl ether (17.3 ml, 1.0 M, 17.3 mmol, 3.0 eq) was carefully added over twenty minutes to a solution of 3-cyclopropyl-4-methoxybenzonitrile (2-2, 1.0 g, 5.77 mmol, 1.0 eq) in tetrahydrofuran (28.9 ml) at 0° C. under nitrogen atmosphere. The resulting dark orange mixture was allowed to stir at 0° C. for 30 min, then carefully quenched in the following order: water (1.0 ml), 15% NaOH aqueous (1.0 ml) and water (3.0 ml). The resulting emulsion was stirred at room temperature for 30 min. Several spatula amounts of magnesium sulfate was added to the mixture to remove any water. The entire mixture was filtered through a pad of sodium sulfate, washing with ethyl acetate. The collected filtrate was concentrated to give the product (2-3) as a yellow oil. ESI+MS [M-16]+ C11H15NO: 161.1 found, 161.2 required.
