Reaction Steps

To a stirring solution of 2-[(1-Boc-piperidin-4-ylcarbonyl)amino]-5-methylsulfonyliodobenzene (1.89 g, 3.72 mmol) in acetonitrile (50 mL) was added K2CO3 (2.53 g. 18.6 mmol) followed by Pd (PPh3)4 (0.22 g, 0.19 mmol) and CuI (0.036 g, 0.19 mmol). The mixture was placed under an atmosphere of CO and heated to 75° C. After 2 h, the heat was removed and the mixture was diluted with ethyl acetate and washed with water, then brine. The organic phase was then dried with MgSO4, filtered and concentrated in vacuo. The residue was chromatographed over silica gel, eluting with a gradient of 10% to 20% ethyl acetate in dichloromethane. The product containing fractions were combined and concentrated in vacuo to give 0.485 g (32%) of a white solid.
