Reaktionsschritte
2,6-Dimethyl-5-iodo-4(3H)-pyrimidinone and 4-ethynyl-α,α,α-trifluorotoluene were reacted in toluene in the presence of dichlorobis(triphenylphosphine)palladium, cuprous iodide, and triethylamine while stirring under room temperature to heating to obtain a compound. The compound was mixed with POCl3 and reacted while heating under reflux to obtain a target substance. The target substance was subjected to e.g., proton nuclear magnetic resonance spectrometry (1H-NMR) and mass spectrometry (MS) and confirmed as the titled compound. Furthermore, MS measurement result is shown.
