Procedure

To a cooled solution (0° C.) of #204 (8.0 g, 10.77 mmol, 1 eq.) in dichloromethane (25 mL) was added dropwise diisopropylethylamine (5.6 g, 43.08 mmol, 4 eq.) followed by a solution of #103 (3.22 g, 10.77 mmol, 1 eq.) in dichloromethane (15 mL). After the addition, the mixture was stirred at room temperature for 16 hours and the solvent was removed in vacuo. The residue was purified by silica gel chromatography (Gradient: 1 to 10% methanol in dichloromethane) to give #205 (2.2 g, 33%) as a yellow solid HPLC (Protocol X): m/z 597.42 [M+H+], retention time=8.729 minutes (purity >97%), Chiral HPLC retention time: 2.87 min (purity=89%) Column: Chiralcel OD-3, 150×4.6 mm, 3 μm; Mobile phase: ethanol (0.05% diethylamine) in CO2 from 5% to 40% over 12 minutes; Flow rate: 2.5 mL/minute.
