Steps:
I Synthesis of Core 1-5-1
1,4-Dibromobenzene (10 g, 42.4 mmol) into a THF (100 ml) in a nitrogen stream -78°C From 2.5M n-BuLi (16.9 ml, 42.4 mmol) slowly into the stirring for 2 hours now and, at -78°C dichlorodiphenylsilane (4.9 g, 19.3 mmol) slowly into the stirring for 2 hours at room temperature after 12 hours stirring. EA and extracted with waterBack, and then dried over MgSO4, and concentrated to the resulting organic ilicagel column and recrystallization to give the desired compound 9.2 g (96%).
