反応手順

4-hydroxy-4-methylcyclohexanone (270 mg, 1.48 mmol) was dissolved in 1,2-dichloroethane (8.3 ml), followed by sequential addition of benzylamine (0.2 ml, 1.83 mmol), NaBH(OAc)3 (560 mg, 2.66 mmol), and acetic acid (0.1 ml, 1.66 mmol), and then the resulting mixture was stirred at room temperature under nitrogen stream for 72 hours. The resulting reaction liquid was neutralized by addition of 10% aqueous NaOH solution, and extracted with 5% MeOH/MC (50 ml×3). The organic layer was dried over anhydrous sodium sulfate, followed by filtration and concentration, and then the residue thus obtained was subjected to MPLC (10% MeOH/MC), to obtain 350 mg of yellow solid (96%).
