6-Bromo-2-(3,5-dimethylphenyl)quinoline (5.3 g, 16.98 mmol) and 150 mL anhydrous THF were added in a dry two-necked round bottom flask and cooled down to −78° C. 7.2 mL BuLi (2.5 M) was added dropwise. The solution was stirred for 45 minutes and 4.4 mL (20.37 mmol) of chlorotriisopropylgermane was slowly added with a syringe. The solution was stirred for 4 h and monitored by GC until the reaction was finished. The reaction mixture was purified by column and distillation. ˜6.1 g colorless liquid was obtained after distillation. GC-MS confirmed the desired product.
