YieldReaction ConditionsOperation in experiment
92% A solution of 9-fluorenylmethyl carbazate (223 mg, 0.879 mmol), Boc-D- Bip-OH (300 mg, 0.879 mmol), HBTU (400 mg, 1.054 mmol), and DIEA (0.31 mL, 1.757 mmol) in DMF (3.0 mL) was stirred at room temperature under nitrogen for 18 hours. The solution was treated with TAEA (0.5 mL) and stirring was continued for 2 hours. The volatiles were removed under vacuum and the resulting residue was purified by HPLC on a Phenomenex Luna Cl 8(2) column (41.2 x 250 mm) using a 0.9percent/min gradient of 27 to 54percent acetonitrile containing 0.1percent TFA) at a flow rate of 80 mL/min. The main product peak eluting at 18.1 minutes was lyophilized to give the title compound as a colorless solid (170 mg, 92percent, HPLC purity 100percent). MS (ESI): 256.4 (40, M-Boc+H), 300.3 (100, M-t-Bu+H), 378.3 (10, M+Na); HRMS: Calcd for C20H26N3O3 (M+H): 356.1969; Found: 356.1968.
