Reaction Steps

Dioxane (12 ml) was added to a mixture of 5-iodo-2-(3-methoxyazetidin-1-yl)pyrimidine (1.14 g), tert-butyl 3-oxopiperazine-1-carboxylate (941 mg), rel-(1R,2R)-N,N′-dimethyl cyclohexane-1,2-diamine (223 mg), copper iodide (149 mg), and potassium phosphate (2.5 g), followed by stirring at 100° C. overnight. The reaction mixture was cooled to room temperature and then filtered by the addition of CHCl3 and Celite, and the filtrate was concentrated. The obtained residue was purified by basic silica gel column chromatography (EtOAc/hexane) to obtain tert-butyl 4-[2-(3-methoxyazetidin-1-yl)pyrimidin-5-yl]-3-oxopiperazine-1-carboxylate (867 mg).
