Reaction Steps

At −78° C., n-butyl lithium (2.5 ml/L, 3 ml) was slowly added dropwise into a solution of tert-butyl 4-bromo-3-((dimethylamino)methyl)phenylcarbamate (compound 28) (2.7 g, 8 mmol) in THF. The reaction mixture was stirred at low-temperature for 30 minutes, followed by adding trimethylchlorosilane (1.1 g, 9.6 mmol). And then the reaction mixture was stirred at low-temperature for 1 hour. After the mixture was warmed to RT and stirred overnight, three times of water was added into the reaction solution. The reaction mixture was extracted by ethyl acetate. The solvent was dried and evaporated to give a crude product, which can be directly used for the next step.
