Reaction Steps

A mixture of 0.20 g (0.56 mmol) of [1-(5-iodo-pyridin-2-yl)-cyclopropyl]-carbamic acid tert-butyl ester, 22 mg (0.12 mmol) of CuI, 0.035 mL (0.22 mmol) of 1,2-trans-di(methylamino)cychlohexane, 0.090 mg (1.1 mmol) of cyclopropanecarboxamide, and 0.24 mg (1.1 mmol) of K3PO4 in 1 mL of 1,4-dioxane was heated under an N2 atmosphere for overnight at 110° C. The mixture was cooled, diluted with 10 mL of EtOAc, and washed with aq. NH4Cl/NH4OH (pH 8), then with aq. NH4Cl. The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was triturated with acetonitrile to provide 98 mg (56%) of {1-[5-(cyclopropanecarbonyl-amino)-pyridin-2-yl]-cyclopropyl}-carbamic acid tert-butyl ester as an off-white powder.
