Ammonia → [4-(2-Piperidin-1-ylethoxy)phenyl]methanol

Participants

Reaction Steps

To a suspension of lithium aluminum hydride (1.5 g) in tetrahydrofuran (50 ml) under a nitrogen atmosphere was added 4-(2-piperidin-1-ylethoxy)benzoic acid ethyl ester (5.0 g) on an ice bath, and the solution was refluxed for 1 hour. Ammonia solution was added thereto on an ice bath, the solution was filtered through celite pad, then the solvent was evaporated in vacuo, and [4-(2-piperidin-1-ylethoxy)phenyl]methanol (3.5 g) was obtained. To a solution of this compound (1.7 g) in chloroform (30 ml) was added manganese(IV) oxide (7.5 g), the solution was stirred overnight at room temperature, then filtered, and the solvent was evaporated in vacuo to provide the title compound (1.7 g).
