Reaction Conditions:

with tripotassium phosphate tribasic;copper (I) iodide;(±)-trans-1,2-diaminocyclohexane in toluene; for 4 h;

Steps:

A1-1 Synthesis of Intermediate A(1)-P3

Carbazole (40 g, 1 eq.), 1-bromo-2-iodobenzene (70 g, 1.5 eq.), CuI (6.3 g, 0.2 eq.), K₃PO₄(70 g, 2 eq.), trans-1,2-cyclohexanediamine (19 g, 1 eq.) and toluene (600 ml) were introduced to a 1-neck-round bottom flask (1-neck-r.b.f), and stirred for 4 hours. (0137) The reaction solution completed with the stirring was filtered only with methylene chloride (MC), and then column separated to obtain P3 (approximately 65 g). (0138) Step yield=96%
