Reaction Conditions:
with tetrakis(triphenylphosphine) palladium(0);potassium carbonate in tetrahydrofuran;water at 80; for 12 h;Inert atmosphere;
Steps:
32 Synthesis Example 32: Synthesis of Intermediate I-32
Synthesis Example 32: Synthesis of Intermediate I-32 The compound, 2-chloro-4,6-diphenyl-1,3,5-triazine (50 g, 187 mmol) was dissolved in THF (1 L) under a nitrogen environment, (4-bromophenyl)boronic acid (45 g, 224.12 mmol, Aldrich Corporation), and tetrakis(triphenylphosphine)palladium (2.1 g, 1.87 mmol) were added thereto, and the mixture was stirred. Potassium carbonate saturated in water (64 g, 467 mmol) was added thereto, and the obtained mixture was heated and refluxed at 80° C. for 12 hours. When the reaction was complete, water was added to the reaction solution, and the mixture was extracted with dichloromethane (DCM) and then, filtered after removing moisture with anhydrous MgSO4 and concentrated under a reduced pressure. This obtained residue was separated and purified through flash column chromatography to obtain Compound I-32 (70 g and 96%). HRMS (70 eV, EI+): m/z calcd for C21H14BrN3: 387.0371. found: 387. Elemental Analysis: C, 65%; H, 4%
