Reaction Steps
1.25 g (4 mmol) of tri-o-tolylphosphine, 8.5 ml of triethylamine, 230 mg (1 mmol) of palladium acetate and 9 ml of tert-butyl acrylate are added to a solution of 10 g (20.5 mmol) of methyl 3-(3-bromo-6-{[(4-chlorophenyl)sulphonyl]amino}-5,6,7,8-tetra-hydro-1-naphthyl)propanoate, described in Application EP 864 561, in 250 ml of DMF. The reaction mixture is stirred at 110° C. for 8 hours. The solvent is then evaporated off, and purification by chromatography on silica gel, using as eluant a cyclohexane/ethyl acetate mixture (80/20), yields the expected product.
