A mixture of N-tertiary-butyloxycarbonyl-N-methyl4-iodoaniline (11 g, Reference Example 9), tert-butyl acrylate (8.4 g), tris-(o-tolyl)phosphine (500 mg), palladium (II) acetate (150 mg), and triethylamine (7 g) in DMF (20 mL) was stirred at 90° C. under nitrogen overnight. The reaction mixture was cooled to room temperature then partitioned between ethyl acetate (500 mL) and hydrochloric acid solution (500 mL, 1M). The organic phase was dried and then evaporated. The residue was crystallised from cyclohexane to give the title compound (7.4 g) as a white solid.
