Versuchsvorschrift
To a solution of 3-aminopyridine (10 g, 0.106 mol) and triethyl amine (16.3 mL, 0.117 mol) in dichloromethane (100 mL) at 0° C., was added benzyl chloroformate (15.2 mL, 0.106 mol) slowly. The reaction mixture was stirred overnight and was washed with water, saturated NaHCO3, dried over MgSO4, and evaporated. The residue was purified on a silica gel column to give the product (9.51 g)
