الإجراء التجريبي

Phenyl chloroformate (0.733 mL, 5.84 mmol) is suspended in pyridine/DCM (3 mL, 2:1). The solution is stirred at 0° C., and 3-aminopyridine (500 mg, 5.31 mmol) dissolved in DCM (1 mL) is added dropwise. The reaction mixture is at 0° C. for 1 hour. The solvent is removed in vacuo and the residue is dissolved in ethyl acetate. This organic portion is washed with 0.1 M HCl and then concentrated in vacuo to afford the titled compound. (MH+215)
