Participants

Reaction Steps

To a solution of intermediate 448.1 (1.74 g, 2.60 mmol) in 10 mL THF at rt, was added TBAF (1M in THF, 2.60 mL, 2.60 mmol). The mixture was stirred at rt for 30 min, then was diluted with EtOAc, washed with H2O (2×) and brine, dried (Na2SO4) and concentrated. The crude product was triturated with hexanes (10 mL) to afford after filtration 1.32 g of intermediate 448.2 as a white solid. LCMS (2 min gradient) RT=1.81 min, 555.3 (M+H)+.
