実験手順

6-Bromo-2-(3,5-dimethylphenyl)quinoline (6.0 g, 19.2 mmol) and 150 mL anhydrous THF were added in a dry 2-necked round bottom flask and cooled down to −78° C. 8.46 mL BuLi (2.5 M in hexane) was added dropwise. The solution was stirred for 45 minutes at −78° C. and 2.83 mL (23.06 mmol) of chlorotrimethylgermane was slowly added with a syringe. The solution was stirred for overnight. The reaction mixture was purified by column 5% ethyl acetate in hexane and distillation. ˜4.1 g white slide was obtained after recrystallization from hexane. GC-MS confirmed the desired product.
