Reaction Steps
To a chilled (−78° C.) solution of acetonitrile (MeCN) (1.13 mL, 4 equiv) in THF (54 mL) was added butyllithium (BuLi) (1.62 mL, 10 M in hexanes, 3 equiv) dropwise, keeping the temperature under −60° C. The mixture was stirred for 15 minutes at −78° C. A solution of 4-(((tert-butyldimethylsilyl)oxy)methyl)benzoyl chloride (1.44 g) in THF (5 mL) was slowly added, and the reaction mixture was stirred at −78° C. for 45 minutes. The reaction was then quenched with aqueous ammonium chloride and diluted with EtOAc. The phases were separated and the organic phase was washed with brine, dried over sodium sulfate, and concentrated onto silica gel. Purification by silica chromatography (9:1 hexanes:EtOAc to EtOAc) provided the title compound (370 mg, 24% yield) and the de-silylated product (330 mg).
