実験手順
To a solution of (±)-tert-butyl {[cis-4-(1-hydroxy-3-phenylpropyl)cyclohexyl]methyl}carbamate (3.63 g, approximately 10 mmol) in dioxane (20 ml) cooled in an ice-bath was added dropwise 4M hydrogen choride in dioxane (20 ml, 80 mmol). The solution was stirred 2 hours at ice-bath temperature, one hour at ambient temperature, then concentrated at reduced pressure. The solid residue was taken up in methylene chloride (200 ml) and 10N sodium hydroxide (1.0 ml, 10 mmol) was added. The mixture was stirred 20 minutes at ambient temperature, dried (sodium carbonate and sodium sulfate), filtered, and the solvent evaporated under reduced pressure to give crude (+−)-1-[cis-4-(aminomethyl)cyclohexyl]-3-phenylpropan-1-ol (2.71 g, theoretical yield 2.47 g) as a yellow gum: 1H NMR (CDCl3) 7.28 (2H, m), 7.18 (3H, m), 3.51 (1H, m), 2.85 (1H, m), 2.64 (3H, m), 1.88 (1H, m), 1.69 (1H, m), 1.54-1.33 (3H, m). MS: 248.3 (M+1).
