A mixture of 6.05 g (19.3 mmol) (6-chloro-4-iodo-pyridin-3-yl)-methyl-amine, 23.6 g (23.6 mmol) 2-chlorophenylboronic acid, 441 mg (1.96 mmol) palladium(II) acetate, 1.03 g (3.93 mmol) triphenylphosphine, 47.1 ml 2 N sodium carbonate solution and 50 ml 1,2-dimethoxyethane was heated at 80° C. for 90 min. The reaction mixture was cooled to room temperature and diluted with 100 ml ethyl acetate. The aqueous layer was separated and extracted with 100 ml ethyl acetate. The combined organic layers were dried over sodium sulfate, concentrated in vacuo and purified by flash chromatography to give 4.1 g (83%) of the title compound as a light brown solid.
