Reaction Conditions

Reaction Steps

N,N-dimethylacetamide (200 mL) was added to Pd-118 (1.009 g) and tetrabutylammonium chloride hydrate (0.916 g), followed by 2-(3-bromo-4-methoxyphenyl)acetonitrile (7 g). Methyl 3-hydroxy-2-methylenebutyrate (5.64 mL) and dicyclohexylamine (9.25 mL) were added and the solution was heated at 80° C. for 3 days. The reaction mixture was diluted with EtOAc (200 mL) and extracted with water. The organic phase was dried, filtered and evaporated under reduced pressure. The crude product was purified by chromatography to afford the subtitle compound as an orange oil, 5.01 g.
