Procedure

A flask was charged with zinc cyanide (129 mg, 1.10 mmol) and tetrakis(triphenylphosphine)palladium(0) (63 mg, 0.0547 mmol). Under an atmosphere of argon, a solution of the compound of step 1 (400 mg, 1.10 mmol) in DMF (1.9 ml) was added to the mixture. After stirring at 150° C. for 1 h and cooling, the mixture was diluted with methyl tert-butyl ether and filtered over celite. The filtrate was washed with water, dried over magnesium sulfate, filtered and evaporated to dryness to give 275 mg of the title compound.
