Procedure
A stirred mixture of 1-8 (71 mg, 0.20 mmol), 1-9 (59 mg, 0.22 mmol) (Rico et al., J. Org. Chem., 1993, 58, 7948), NMM (88 μL, 0.8 mmol), and CH3CN (25 mL) was treated with BOP (97 mg, 0.22 mmol). After 24 h, the reaction mixture was concentrated to dryness, dissolved in EtOAc, and then washed with H2O, dried (MgSO4), and concentrated. Flash chromatography (silica, 10% (NH3/EtOH/EtOAc) gave 1-10 as a colorless gum.
