실험 절차

To a solution of 3-phenylpropyl isocyanate (1.8 mmol) in anhydrous THF (10 mL) at 0° C. under an argon atmosphere was added 2-aminomethyl-pyridine (1.8 mmol). The reaction mixture was stirred at 0° C. for 10 min, the solvent was evaporated under reduced pressure, and the resultant solid was recrystallized from CH2Cl2/Et2O to give pure 59.1 in 92% yield. White solid. m p 89-90° C. When anhydrous benzene was used as solvent the product was directly crystallized out and isolated by filtration (93% yield).
