실험 절차

A solution of the title compound of step 3 (10.0 g, 41.1 mmol) in dry THF (70 mL) was slowly added to a mixture of LiAlH4 (1.87 g, 49.3 mmol) in dry THF (25 mL) in a protective gas. The mixture was then stirred for 3 h with reflux. After the reaction mixture had cooled, a solution of water (1.87 mL, 104 mmol) diluted with a little THF was added in drops with ice cooling and subsequently stirred for 10 min. 15% aqueous NaOH (1.87 mL, 8.17 mmol) diluted with a little THF was then added in drops and water (5.6 mL) was then added again. The precipitate formed was filtered over diatomaceous earth and the solvent removed in a vacuum. The amine remained as residue.
