In this study, the synthesis of the planned compounds was carried out in two steps. In the first step, 1-methylimidazole-2-carbaldehyde compound was reacted with thiosemicarbazide and thiosemicarbazone compound was obtained. In the second step, the thiosemicarbazone compound obtained in the first step was reacted with 2-bromoacetophenone derivative compounds and thiazole derivative compounds were obtained. The structures of the synthesized compounds were confirmed by 13C NMR, 1H NMR and HRMS spectral findings, and the melting point was determined for these compounds. The % inhibition values of the compounds on the enzyme acetylcholinesterase (AChE) and butyrylcholinesterase (BuCHe) were investigated.
