実験手順

4-hydroxycyclohexanone (443 mg, 3.88 mmol) was dissolved in 1,2-dichloroethane (20 ml), followed by sequential addition of cyclopropylamine (0.295 ml, 4.27 mmol), NaBH(OAc)3 (1.3 g, 6.21 mmol), and acetic acid (0.2 ml, 3.88 mmol), and then the resulting mixture was stirred at room temperature under nitrogen stream for 13 hours. The resulting reaction liquid was neutralized by addition of 10% aqueous NaOH solution, and extracted with 10% MeOH/MC (15 ml×4). The organic layer was dried over anhydrous sodium sulfate, followed by filtration, concentration, and vacuum drying, to obtain 580 mg of yellow solid (96%).
