3-BROMO-1-(TRIISOPROPYLSILYL)PYRROLE Use and Manufacturing
NBS (3.25 g, 18.3 mmol) was added to the solution of the above product (3.72 g, 16.6 mmol) in THF (17 mL) at -78 °C, and the whole mixture was stirred for 5 hr. n-Hexane (15 mL) and pyridine (0.5 mL) was added to the mixture, and the whole mixture was stirred for 5 min. Removal of the solvent from the reaction mixture gave a crude product, which was purified by SiO2 column (n-hexane/AcOEt = 30:1) to give 3-bromo-1-triisopropylsilanyl-1H-pyrrole 2 (4.67 g, 93percent) as a colorless oil.To a solution of the above prepared 1-(triisopropylsilyl)-1H-pyrrole (5.85 g, 26.2 mmol) in THF (50 mL) was added NBS (4.66 g, 26.2 mmol) at −78° C. and the resulting mixture was stirred at −78° C. for 2 h. The mixture was warmed to room temperature and stirred for additional 1 h. The mixture was concentrated and purified by column chromatography on silica gel (petroleum) to give compound 0601-197 (6.8 g, 63percent) as a colorless oil. LCMS: 302 [M+1]In THF prepared above 1- (triisopropylsilyl) pyrrole-lH (5.85g, 26.2mmol) (5The solution in 0 mL), was added NBS (4.66g, 26.2mmol) at -78 ° C., and the resulting mixture was stirred for 2 hours at -78 ° C.. The mixture was allowed to warm to room temperature, the mixture was stirred for a further 1 hour. The mixture was concentrated by column chromatography on silica gel and purified by (petroleum) to give the compound 0601-197 as a colorless oil (6.8 g, 63percent).
