Reaction Steps

To a dichloromethane (10 mL) solution of 4-nitrophenyl chloroformate (812 mg), a dichloromethane (10 mL) solution of 6-amino-2N-Boc-1,2,3,4-tetrahydroisoquinoline (1.00 g) and pyridine (0.33 mL) was gradually added at 0° C. The reaction mixture was stirred at 0° C. for 1 hour and at room temperature for 2 hours and then concentrated. The residue was vigorously stirred in a mixed solution of diisopropyl ether and water (diisopropyl ether/water). The precipitate was collected by filtration and dried under reduced pressure to obtain the title compound (1.46 g, 88%) as a yellow solid.
