Procedure
A solution of (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-3-[2-(2-bromobutanoyl)-5-(trifluoromethyl)benzyl]-4-methyl-1,3-oxazolidin-2-one (25 mg, 0.040 mmol) and methyl 4-(aminocarbonothioyl)-3-methylbenzoate (16.87 mg, 0.081 mmol) in EtOH (450 μL) was heated at 70° C. overnight. The reaction was concentrated in vacuo and the residue was purified by preparative TLC (Si, 1000 microns, Hex/EtOAc (80:20)) to afford methyl 4-{4-[2-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-4-(trifluoromethyl)phenyl]-5-ethyl-1,3-thiazol-2-yl}-3-methylbenzoate, as colorless oil.
