Versuchsvorschrift

To a cold (0° C.) solution of 1-cyclopropylmethyl-piperidin-4-one (314 mg, 2 mmol, 1.0 eq.) in ethanol (4 mL) was added sodium borohydride (61 mg, 2 mmol, 0.75 eq.). The reaction mixture was stirred 16 h at room temperature. Water, sodium hydroxide and dichloromethane were added and the reaction mixture was stirred 2 h at room temperature. The aqueous layer was extracted with dichloromethane and the combined organic phases were dried over sodium sulfate, filtered then concentrated to dryness in vacuo to yield 160 mg (50%) of the tide compound as colorless oil, witch was used in the next step without further purification. MS (m/e): 156.3 (MH+, 100%).
