To the crude DMF solution of the boronate from Step 1 was added 2-benzyloxy-3-bromopyridine (0.25 g), aqueous sodium carbonate solution (2M, 2.8 mL) and dioxane (4 mL) and the mixture placed under argon. [1,1-bis-(diphenylphosphino)-ferrocene]-dichloropalladium-dichlormethane-complex (0.070 mg) was added and the mixture heated at 110° C. under microwave irradiation for 30 minutes. On cooling the mixture was partitioned between DCM and water and extracted. The organic portion was washed with brine, dried and concentrated in vacuo. Purification was achieved by chromatography on silica gel to give the title compound (138 mg).
