Procedure

A solution of 6-{4-[3-(2,5-dioxoimidazolidin-1-yl)phenyl]butoxy}hexyl methanesulfonate (766 mg) in DMF (8 ml) was treated with tetrabutylammonium bromide (578 mg) and (1R)-2-amino-1-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)ethanol (544 mg) and the mixture was stirred at 20° C. for 3 d. The solvent was removed under reduced pressure, the residue was dissolved in CH2Cl2, washed with water and purified by chromatography on Biotage (40 g) eluting with 3% 2M NH3 in MeOH:CH2Cl2 to give the title compound (417 mg). ES+ve 554 (MH)+.
