Yield:1160294-96-1 83%

Reaction Conditions:

with tris-(dibenzylideneacetone)dipalladium(0);tri-tert-butyl phosphine;potassium tert-butylate in toluene at 85; for 2 h;

Steps:

Synthesis of Intermediate I-14
3 g of intermediate I-13,3 g of [1,1'-biphenyl] -4-amine,360 mg of Pd2 (dba) 3,0.4 mL of 1 M P (t-Bu) 3 and 2.7 g of KOtBu were dissolved in 75 mL of toluene,And the reaction solution was stirred at a temperature of 85 ° C for 2 hours.The resulting reaction solution was cooled to room temperature, and the reaction was completed by adding water thereto,The organic layer was extracted three times by using ethyl acetate.The organic layer thus collected was dried over anhydrous magnesium sulfate,And the residue obtained after filtration under reduced pressure was separated and purified by silica gel column chromatography to obtain 3.5 g of intermediate I-14 (yield: 83%).The compounds thus produced were determined by using LC-MS.
