Reaction Steps

A mixture of (31) (4 g, 11.6 mmol), diethyl 3-pyridylborane (2.04 g, 13.9 mmol), potassium carbonate (4.8 g, 34.8 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.2 g) in a mixture of water (20 ml) and dimethoxyethane is stirred at 80° C. in a nitrogen atmosphere overnight. After cooling the resulting suspension is poured into water and the crude product is filtered off, washed with water and dried. Purification is achieved by column-chromatography on silica gel using a mixture of ethyl acetete and methanol (9:1) as the eluent. Yield 2.46 g (72%) of the title compound. Mp.191-193° C.
