Participants

Reaction Steps

DEAD (0.6524 mL, 4.143 mmol) was added to a solution of (3-(8-(tert-butyldimethylsilyloxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-7-yl)methanol (1.123 g, 2.762 mmol), isoindoline-1,3-dione (0.6096 g, 4.143 mmol) and triphenylphosphine (1.087 g, 4.143 mmol) in THF (20 mL) at 0° C. Following addition, the cold bath was removed and the reaction stirred at ambient temperature for 3 hours. The crude reaction was concentrated and the residue was purified by flash column chromatography (eluting with at 1:4 mixture of ethyl acetate/Hexanes) to afford the desired product mixed with triphenylphosphine oxide.
