Participants

Reaction Steps

To 39A (640 mg, 2.043 mmol), N,N-diisopropylethylamine (1.424 ml, 8.17 mmol) in DMF (10 ml), was added N-(benzyloxycarbonyloxy) succinimide (560 mg, 2.248 mmol). The mixture was stirred at rt for 1 h, quenched with water, extracted with EtOAc. The organic layer was washed with brine, dried (Na2SO4) and concentrated. The crude product was purified by flash chromatography to give 39B (540 mg, 1.442 mmol, 70.6% yield). MS (ESI) m/z: 375.2 (M+H)+.
