Procedure

A suspension of 2-chloro-7H-pyrrolo-[2,3-d]pyrimidine 3 (0.53 g, 3.5 mmol), 2-bromopyridine (0.66 mL, 1.1 g, 6.9 mmol), copper(I) iodide (0.20 g, 1.0 mmol), trans-1,2-diaminocyclohexane (0.12 mL, 0.1 Ig, 1.0 mmol), and potassium phosphate (2.2 g, 10 mmol) in 10 mL 1,4-dioxane is heated to 100° C. and stirred for four hours. The reaction mixture is cooled to room temperature, diluted with ethyl acetate, and washed with water and brine. The organic extract was dried over MgSO4, filtered, and concentrated under reduced pressure. Purification by column chromatography (SiO2, Hexane : Ethyl acetate/5:1) provided 4 (0.69 g, 87%) as a white solid.
