To a solution of 3-aminobenzylamine (610 mg, 5 mmol) and TEA (1.01 g, 10 mmol) in 10 mL of THF at 0° C., was added benzyl chloroformate (936 mg, 5.5 mmol) dropwise. The mixture was stirred at rt for 30 min. The reaction was quenched with water and extracted with EtOAc (3×20 mL). The organic layer was washed with brine, dried (Na2SO4) and concentrated. Purification via flash chromatography (0 to 50% EtOAc in hexanes) gives 66A (911 mg, 71%). MS (ESI) m/z 257.3 (M+H)+.
