Reaction Steps

1-Iodo-4-nitrobenzene (1.61 g, 6.45 mmol) was combined with 3-methyl-2-pyridone (0.845 g, 7.74 mmol), CuI (0.246 g, 1.29 mmol), and K3PO4 (2.74 g, 12.9 mmol). 1,4-Dioxane (6 mL) was added followed by trans-1,2-diaminocyclohexane (0.194 mL, 1.61 mmol). The mixture was heated to reflux for 19 h before cooling and diluting with EtOAc. The mixture was filtered through a plug of silica, eluting with EtOAc, and the filtrate concentrated under reduced pressure. Purification of the crude product by flash chromatography provided 159-a (0.528 g, 36%) as a brown solid. MS: APCI (AP+): 231.1 (M)+.
