Procedure

To a solution of 1-{benzyl-[1-(4-butylamino-benzenesulfonyl)-azetidin-3-yl]amino}-3-(4-benzyloxy-phenoxy)-propan-2-ol (0.10 g, 0.15 mmol) in N,N′-dimethylpropyleneurea (1 ml) was added methyl bromoacetate (46 mg, 0.3 mmol) and potassium carbonate (28 mg, 0.2 mmol), and the mixture was stirred at 50° C. for 2 days. It was then cooled to room temperature and diluted with water (20 ml). The aqueous phase was removed, and the residue dissolved in ethyl acetate (20 ml). The organic solution was washed with brine, and dried over anhydrous sodium sulfate. It was then filtered and evaporated, and the residue was chromatographed on silica gel (ethyl acetate-hexanes/1:1) to give 50 mg of a colorless gum; MS (ES) m/z 702.2 (MH+); HRMS (FAB) Calcd. for C39H48N3O7S (MH+): 702.3213, Found: 702.3231.
