Reaktionsschritte

4-Hydroxy-4-methylcyclohexanone (440 mg, 3.43 mmol) was dissolved in 1,2-dichloroethane (15 ml), followed by sequential addition of cyclopropylamine (0.26 ml, 3.78 mmol), NaBH(OAc)3 (1.16 g, 5.49 mmol), and acetic acid (0.20 ml, 3.43 mmol), and then the resulting mixture was stirred at room temperature under nitrogen stream for 20 hours. The resulting reaction liquid was neutralized by addition of 10% aqueous NaOH solution, and extracted with 5% MeOH/MC (15 ml×4). The organic layer was dried over anhydrous sodium sulfate, followed by filtration, concentration, and vacuum drying, to obtain 417 mg of yellow solid (72%).
