Procedure
The procedure In Example 4 is followed but using 4,6-diphenyl-2-pyridinone (4 g), methyl 6-bromo-2,2-dimethylhexanoate (5.8 g) (prepared according to the method described in Patent EP 108 592), silver carbonate (2.3 g) and toluene (150 cc). The product is purified by chromatography under pressure on silica gel (30-60 mm; eluent: n-hexane-ethyl acetate 95-5, brown oil)
