Procedure

2d (99 mg, 0.35 mmol), 56a (92 mg, 0.35 mmol) and diisopropylethylamine (0.1 mL, 0.6 mmol) were combined in 0.5 mL of DMSO and stirred at room temperature for 18 h. The mixture was diluted with aqueous NaHCO3 (5 mL) and extracted with EtOAc (5 mL). The organic layer was concentrated under vacuum to afford the crude 56b. 20 mg of this crude material was purified by preparative HPLC to afford 56b: LC-MS 488.3 (MH+).
