Reaction Steps

A mixture of (4-(diphenylamino)phenyl)boronic acid (1.5 g, 5.19 mmol), 4-iodo-1-bromobenzene (1.33 g, 4.71 mmol), Na2CO3 (1.78 g, 16.8 mmol) and Pd(PPh3)4 (0.163 g, 0.141 mmol) in THF/H2O (28 mL/17 mL) was degassed and the resulting mixture was heated at reflux overnight under an argon atmosphere. After cooling, the mixture was poured into dichloromethane (150 mL), then washed with water (2×150 mL) and brine (100 mL). The organic phase was dried over Na2SO4, purified with flash column chromatography (silica gel, hexanes/ethyl acetate 50:1) then recrystallized in dichloromethane/methanol to afford a white solid (Compound 35)(1.64 g, in 87% yield).
