Reaction Steps
To a solution of (S)-tert-butyl 1-(tert-butyldimethylsilyloxy)but-3-en-2-yl(2-(methoxy(methyl)amino)-2-oxoethyl)carbamate (Intermediate 5, 10.7 g, 26.58 mmol) in THF (25 mL) was added TBAF (31.9 mL, 31.89 mmol) at 0° C. After 1 hour the reaction mixture was concentrated and purified by silica gel chromatography (hexanes/ethyl acetate) to afford the product as a light yellow oil (5.9 g, 77%).
