Reaction Steps

A mixture of (5S)-2-(cis-4-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)-2,7-diazaspiro[4.5]decan-1-one (0.282 g, 0.000769 mol), 4-bromo-2-chloro-1-iodobenzene (0.293 g, 0.000922 mol) (Lancaster, cat #: 19245), copper(I) iodide (0.015 g, 0.000077 mol), potassium phosphate (0.490 g, 0.00231 mol) and 1,2-ethanediol (0.0857 mL, 0.00154 mol) in 1-butanol (0.75 mL) was heated at 100° C. under nitrogen for 2 d. The reaction mixture was filtered, concentrated under reduced pressure, and the residue was purified by flash chromatography on a silica gel column (eluting with 0 to 50% ethyl acetate in hexanes) to afford the desired product.
