Procedure

A stirred solution of 3-7 (142 mg, 0.4 mmol), 2-9 (110 mg, 0.4 mmol), HOBT (61 mg, 0.4 mmol), N(i-Pr)2Et (216 μL, 1.2 mmol) and DMF (7 mL) at -15° C. was treated with EDC (77 mg, 0.4 mmol) followed by removal of the cooling bath. After 20 h. the reaction mixture concentrated followed by dilution with EtOAc. The EtOAc solution was washed with 1M NaHSO4, and brine, dried (MgSO4), and concentrated. Flash chromatography (silica, 10% to 20% acetone/CH2Cl2) to give 3-8 as a viscous gum. Rf 0.64 (silica, 20% acetone/CH2Cl2).
