Procedure

The product of example 37(0.2 g), bromo-tris(pyrrolidino)-phosphonium hexafluorophosphate (0.38 g), 4-dimethylaminopyridine (0.07 g), methanesulphonamide (0.095 g) and N,N-diisopropylethylamine (0.43 ml) in N,N-dimethylformamide (2 ml) was stirred at room temperature for 16 h. The mixture was partitioned between aqueous tartaric acid and ethyl acetate. The organic solution was dried (MgSO4) and evaporated. Purification was by reverse phase silica gel chromatography (C18-sep-pak) eluting with 50% methanol in 0.1% aqueous ammonium acetate. Yield 0.032 g.
