4-Cyano-2-methylphenylboronic acid (0.81 g, 5 mmol), 6,6-dimethylcyclohex-2-enone (Canadian Journal of Chemistry, 1981, 59, 2096-2115) (0.55 g, 5 mmol), SbCl3 (0.11 g, 0.5 mmol), sodium acetate (0.82 g, 10 mmol), and palladium acetate (0.11 g, 0.5 mmol) are added to acetic acid (30 mL) under an atmosphere of argon. The reaction mixture is stirred at room temperature for three days. The mixture is filtered and the filtrate is poured into water (150 mL). The organic phase is separated and the aqueous phase is extracted with ethyl acetate (3×100 mL). The combined organic layers are washed with saturated sodium bicarbonate solution (3×100 mL), brine (3×50 mL), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue is purified by silica gel column chromatography eluting with pet ether: EtOAc=10:1 to give the title compound as a light yellow solid (0.6 g, 50%). GC/MS 241 (M+1).
