実験手順: To a solution of hydroxylamine-O-sulfonic acid (60.5 g, 535 mmol) in formic acid (320 ml) was added dropwise a solution of 4-isopropyl cyclohexanone (50.0 g, 357 mmol) in formic acid (110 ml) at r.t. under an argon atmosphere. The reaction mixture was refluxed for 3 h, cooled to r.t. and slowly treated with ice-water (550 ml). 10 N NaOH (1.1 liter) was added to adjust the pH to 8 and the resultant mixture was extracted with CHCl3 (4×). The combined organic extracts were washed with water, brine, dried (MgSO4), filtered and concentrated under reduced pressure. The light-brown solid was crystallized from n-heptane: 42.4 g (75%); The reaction mixture was refluxed for 3 h the resultant mixture was extracted with CHCl3 (4×) The combined organic extracts were washed with water, brine dried (MgSO4) filtered concentrated under reduced pressure The light-brown solid was crystallized from n-heptane

実験手順: To a solution of 4-isopropylcyclohexanone (5.0 g, 36 mmol) and benzylamine (3.54 mL, 32 mmol) in MeOH (40 mL) was added 4 Å molecular sieves (2 g). After 16 h at rt NaBH4 (2.45 g, 65 mmol) was added and the mixture stirred for a further 6 h. Water (3 mL) was added and the solvent was removed in vacuo. The residue was partitioned between NaHCO3 (150 mL) and EtOAc (150 mL), the aqueous layer was extracted with EtOAc (2×50 mL) and the combined organic phases were washed with brine (2×50 mL) and dried (MgSO4). Solvent was removed in vacuo and the residue purified by column chromatography (SiO2, NH4OH:MeOH:DCM 0.25:5:95) to give the product as a free base. 4M HCl in dioxane and Et2O were added to the residue, and the resulting precipitate was filtered to give the title compound: δH (CD3OD) 0.92-0.97 (6H, m), 1.17-1.26 (1H, m), 1.53-1.92 (9H, m), 3.21-3.29 (1H, m), 4.23 (2H, s) 7.44-7.54 (5H, m). the solvent was removed in vacuo The residue was partitioned between NaHCO3 (150 mL) and EtOAc (150 mL) the aqueous layer was extracted with EtOAc (2×50 mL) the combined organic phases were washed with brine (2×50 mL) dried (MgSO4) Solvent was removed in vacuo the residue purified by column chromatography (SiO2, NH4OH:MeOH:DCM 0.25:5:95) to give the product as a free base the resulting precipitate was filtered
