With triethylamine; In dichloromethane; at 0℃; | General procedure: Compounds 6a-t were synthesized from substituted benzoic acid via six steps according to the literature method as described. Various substituted benzoic acids 1a-t were treated with SOCl2 to give compounds 2a-t, which were reacted with CH3OH and EtN3 in CH2Cl2 at 0 to afford compounds 3a-t. Compounds 4a-t were prepared by the reaction of compounds 3a-t, hydrazine hydrate in CH3OH under reflux condition about 5h. Subsequently, compounds 5a-t were obtained by reaction of compounds 4a-t with CS2 and KOH in CH3OH. Compounds 6a-t were obtained by the cyclization reaction of compounds 5a-t in the presence of HCl at 0-5°C. |
