6-Chloro-3,3-dimethyl-2,3-dihydro-1H-indole (1 g, 5.5 mmol), zinc cyanide (0.74 g, 6.3 mmol), tris(dibenzylideneacetone)dipalladium (0) (0.2 g, 0.9 mmol) and 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (0.4 g, 1.1 mmol) were combined and dissolved in N-methyl-pyrrolidinone (27.6 mL). The suspension was degassed with nitrogen for 5 minutes. The reaction was heated under microwave irradiation for 2 h at 185° C. then cooled to room temperature and the reaction was diluted with water and extracted with diethyl ether/petrol (1:1) (3×). The combined organic extracts were washed with water and brine, dried over sodium sulfate and concentrated in vacuo. Chromatography (silica gel, gradient elution, 0-100%, EtOAc in petrol 40-60) gave the title compound (0.14 g, 15%) as pale yellow solid. MS: [M+H]+=173.
