Tetrabutylammonium Fluoride Trihydrate → HCID 68640828, compound

Participants

Reaction Steps

A solution of 4-benzyl-4-dimethylamino-1-[3-(2-(triethylsilyl)-1H-indol-3-yl)propyl]cyclohexanol (2.50 g, 4.95 mmol) in anhydrous tetrahydrofuran (25 mL) was mixed with tetra-n-butyl ammonium fluoride trihydrate (6.25 g, 19.8 mmol), boiled with reflux for 7 h and then stirred overnight at room temperature. Since the conversion was not yet complete, the reaction mixture was boiled with reflux for a further 7 h and then stirred over the weekend at room temperature. The reaction mixture was concentrated to low volume in a vacuum and the residue purified by means of flash chromatography (400 g, 20×7.5 cm) with dichloromethane/methanol (95:5+1% conc. aqueous ammonia).
