Reaction Steps

322 mg (0.85 mmol) 4-(4-methoxy-benzyl)-5-oxo-3,4-diaza-bicyclo[4.1.0]hept-2-en-2-yl trifluoro-methanesulphonate dissolved in 4 ml DMSO and some molecular sieve are added to 400 mg (1.69 mmol) 2-phenyl-4,5,6,7-tetrahydro-oxazolo[5,4-C]pyridine. The mixture is stirred for 5 h at 40° C. and then combined with DCM. It is extracted 1× each with sat. sodium carbonate solution and sat. saline solution, the org. phase is dried on magnesium sulphate and the solv. is eliminated by rotary evaporation i.V., the residue is purified through silica gel (eluant: DCM/methanol).
