Reaction Conditions:
with tri-tert-butyl phosphine;bis(dibenzylideneacetone)-palladium(0);sodium t-butanolate in toluene at 90 - 110; for 12 h;Inert atmosphere;
Steps:
1.2 Synthesis of intermediate 5
4-tert-Butyl-1-aniline (14.9 g, 100 mmol),Tert-butyl-1-bromobenzene (21.2 g, 100 mmol),Bis (dibenzylideneacetone) palladium (1.7 g, 3 mmol),Tri-tert-butylphosphine (1.2 g, 6 mmol) was added to toluene (200 ml)And the resulting toluene solution was heated to 90 ° C under a stream of argon;Then sodium tert-butoxide (0.6 g, 6 mmol) was added,Heated to 110 ° C under an argon atmosphere,The reaction was stirred for 12 hours.The reaction mixture was cooled to room temperature,Add water to separate.The solvent of the obtained organic layer was concentrated,Get solid,The resulting solid was purified by silica gel column chromatography,The target product Intermediate 5 (20.2 g, 72 mmol) was obtained,Yield 72%.
