Participants

Reaction Steps

N,N-Diisopropylethylamine (0.169 ml, 0.972 mmol) is added to 4-formylcinnamic acid (0.057 g, 0.324 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.129 g, 0.340 mmol) in DMF (2 ml) and is stirred for 20 minutes at room temperature. 2-[4-(5(S)-aminomethyl-2-oxo-oxazolidin-3-yl)-2-fluorophenyl]-4H-[1,3,4]thiadiazin-5-one (0.100 g, 0.308 mmol) is added and stirring is continued at room temperature overnight. The reaction mixture is partially evaporated under vacuum and the residue is diluted with water (5 ml). The resulting precipitate is filtered and dried under vacuum to give crude product used directly in the next step (0.076 g, 51%). MS (m/z): [M+H]+=483.
