Procedure

1.67 g of the amide of Stage A, 1.39 g of methyl iodo benzoate (Preparation 7), 2.5 g of copper and 4 ml of dimethylformamide were mixed together in an autoclave at 200° C. for 90 minutes. After evaporation of the dimethyl-formamide, extraction was carried out with methylene chloride, followed by concentration under reduced pressure and purification by chromatography on silica, eluting with a cyclohexane/ethyl acetate mixture (7/3) to obtain 337.5 mg of Product A and 766 mg of Product B.
