Procedure

35 mg (0.1 mmol) of N-{[3-(4-aminophenyl)-2-oxo-1,3-oxazolidin-5-yl]-methyl}-5-chloro-2-thiophenecarboxamide (from Example 149) are added to an ice-cooled solution of 26.4 mg (0.15 mmol) of 3-chloro-1-propanesulfonyl chloride and 0.03 ml (0.2 mmol) of triethylamine in 3.5 ml of absolute dichloromethane. After 30 min, the ice cooling is removed and the mixture is stirred at room temperature overnight before adding 150 mg (approx. 5.5 eq) of PS-trisamine (Argonaut Technologies) and 0.5 ml of dichloromethane. The suspension is stirred gently for 2 h and filtered (the resin is washed with dichloromethane/methanol), and the filtrate is concentrated. The product is purified by preparative RP-HPLC. Yield: 19.6 mg (40% of theory),
