실험 절차
A solution of (1R,2S)-2-phenylcyclopropanamine (300 mg, 2.252 mmol) and methyl 4-((3-formylpyrrolidin-1-yl)methyl)benzoate (501 mg, 2.027 mmol) in methanol (50 mL) was heated to reflux for 5 minutes. The reaction mixture was cooled to room temperature and sodium cyanoborohydride (212 mg, 3.38 mmol) was added. The reaction was stirred at room temperature for 16 hours. After concentrating, dichloromethane was added and the solution was washed with water, dried over MgSO4, filtered and concentrated. HPLC purification (reverse phase) was performed with a Gemini NX 5u C18 110A, AXIA. 100×30.00 mm 5 micron column. A 7 minute gradient run (0% AcCN/H2O, 0.1% Formic Acid to 55% ACN/H2O, 0.1% Formic Acid) with UV detection at 214 nm was utilized. Added 1 ml of 1N HCl to fractions containing product and concentrated. Only the desired ester was seen by LC/MS of fractions before concentrating. Obtained 300 mg of a mixture of diastereomers.
