実験手順

A mixture of (5S)-2-(cis-4-hydroxycyclohexyl)-2,7-diazaspiro[4.5]decan-1-one (1.04 g, 0.00412 mol), 4-bromo-2-fluoro-1-iodobenzene (Aldrich, cat #: 283304) (1.85 g, 0.00615 mol), copper(I) iodide (Aldrich, cat #: 215554) (0.122 g, 0.000640 mol), potassium phosphate (2.63 g, 0.0124 mol) and 1,2-ethanediol (0.48 mL, 0.0086 mol) in 1-butanol (3.90 mL) was heated at 100° C. under nitrogen for 2 d. The reaction was quenched with water, and extracted with ether. The organic layers were combined, washed with water, brine, dried over Na2SO4, and filtered. The filtrate was evaporated under reduced pressure. The residue was purified by flash column chromatography on a silica gel column eluting with 0 to 5% methanol in DCM to yield the desired product (950 mg, 54.2%). LC/MS m/e 425.1/427.0 (M+H)+.
