Isopropanol → N-(1,1'-Biphenyl-4-yl)-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)urea

Reaction Steps

A solution of (5R)-3-(6-{2-[(3-aminobenzyl)oxy]ethoxy}hexyl)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-1,3-oxazolidin-2-one (0.202 g) in dichloromethane (4 ml) was treated with 4-biphenylyl isocyanate (0.126 g) and the mixture stirred under nitrogen at 20° C. for 19 h. Isopropanol (15 ml) was added to quench excess isocyanate, and the mixture stirred for 2 h. The solvents were removed in vacuo to give a residue which was purified by Biotage. Elution with 6:4 EtOAc/cyclohexane followed by solvent evaporation in vacuo gave the title compound (0.119 g). LCMS RT=4.09 min, ES+ve 694 (MH)+.
