Reaction Conditions:
with sodium hydride in tetrahydrofuran;mineral oil;
Steps:
In an ice bath, 4-bromo-7-azaindole (25.5 mmol, 5 g) and p-toluenesulfonyl chloride (38.25 mmol, 7.27 g) were added to a reaction flask, dissolved in 100 mL of anhydrous tetrahydrofuran, 60%NaH (30 mmol, 1.2 g) was slowly added, and the mixture was reacted at room temperature for 6 hours. The reaction was stopped, 50 mL of water was slowly added, the organic solvent was dried by rotary evaporation, extracted with dichloromethane, dried over anhydrous Na2SO4, and separated by column chromatography to afford intermediate a2 (9.0 g, quantitative yield), LC-MS: [M + H] +: 350.
