A mixture of 2-(cis-4-hydroxycyclohexyl)-2,8-diazaspiro[4.5]decan-1-one (0.50 g, 2.0 mmol), 4-bromo-1-fluoro-2-iodobenzene (0.894 g, 2.97 mmol), copper(I) iodide (0.0586 g, 0.308 mmol), potassium phosphate (1.26 g, 0.596 mmol) and 1,2-ethanediol (0.23 mL, 4.1 mmol) in 1-butanol (2.5 mL) was heated at 100° C. overnight. The reaction mixture was treated with water, extracted with ether. The combined organic layers were washed with brine, dried over MgSO4 and filtered. The filtrate was concentrated under reduced pressure. The residue was purified on a silica gel column with ethyl acetate in hexane (gradient: 0 to 50%) to give the desired product (0.59 g, 70%). LCMS: (M+H)+=425.0/427.0.
