Procedure

To a mixture of 4-iodo-benzoyl chloride (75 g) in 500 mL CH2Cl2 was added a mixture of Et3N (50 mL) and Et2NH (100 mL) at 0° C. After the addition, the resulting reaction mixture was warmed up to room temperature in 1 hr and was then washed with saturated ammonium chloride. The organic extract was dried (Na2SO4), filtered and concentrated. Residue was recrystallized from hot hexanes to give 80 g of INTERMEDIATE 5.
