実験手順

A solution of [3-(cyclopentylthio)phenyl]methanol (270 mg) in dry DMF (10 ml) under nitrogen was treated with sodium hydride (60% dispersion on mineral oil, 57 mg) and the mixture stirred for 1 h. 2-({6-[(5R)-5-(2,2-Dimethyl-4H-1,3-benzodioxin-6-yl)-2-oxo-1,3-oxazolidin-3-yl]hexyl}oxy)ethyl methanesulfonate (0.4 g) in dry DMF (2 ml) was then added and the mixture stirred for 18 h. Phosphate buffer solution (pH6.5) was added and the mixture extracted with ethyl acetate. The combined extracts were washed with water and dried (MgSO4), filtered, and evaporated in vacuo. The residue was purified on a 10 g silica SPE cartridge, eluting with 10% to 20% ethyl acetate-cyclohexane to give the title compound (0.23 g). LCMS RT=4.08 min.
