Participants

Reaction Steps

To a solution of the alkyne 409 (2.2 g, 5.69 mmol) in THF (30 ml) was added a solution of TBAF (8.53 mL, 1.5 eq, 1M soln in THF) in HOAc (30 ml), and the reaction mixture was stirred at RT overnight. It was then concentrated to dryness and partitioned between water and EtOAc. The organic phase was washed well with satd. NaHCO3 soln, collected, dried over anhydrous Na2SO4, filtered and concentrated. The crude mixture was adsorbed onto silica gel then purified by column chromatography (30% EtOAc in hexane) to afford 410 (1.4 g, 72% yield). LCMS: 415.2 (M+H).
