実験手順

To a solution of 60 gm (349 mMol) cyclohexylacetaldehyde dimethyl acetal in tetrahydrofuran (50 ml) and diethyl ether (100 ml) was added 1N hydrochloric acid (200 ml) and the resulting mixture was stirred for 2.5 hours at room temperature. The reaction mixture was then partitioned between diethyl ether and water. The ether layer was then separated, dried over magnesium sulfate and concentrated under reduced pressure to give 58 gm of crude cyclohexylacetaldehyde.
