Potassium trimethylsilanolate (0.056 g) was added to a solution of N-(3-{[2-({6-[(5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-oxo-1,3-oxazolidin-3-yl]hexyl}oxy)-ethoxy]methyl}phenyl)-N′-phenylurea (0.061 g) in degassed anhydrous THF (4 ml) whilst stirring under nitrogen. The reaction mixture was heated to 65° C. for 4 h, adding additional potassium trimethylsilanolate (0.057 g) and heating for a further 2.5 h, at which point the reaction mixture was cooled to room temperature. Phosphate buffer (20 ml, pH6.5) was added and the mixture extracted with EtOAc (3×20 ml). The combined organic layers were separated and dried over Na2SO4 before filtering. Solvent evaporation in vacuo gave the title compound (0.027 g). LCMS RT=2.80 min, ES+ve 592 (MH)+.
