実験手順: A solution of 1.85 g of 2-amino-5-(1-ethyl-1-methylpropyl)-1,3,4-thiadiazole and 2.21 g of 2,6-diethylbenzoyl chloride in 50 ml of toluene was heated at reflux for sixteen hours and then cooled and the solvent was removed by evaporation under reduced pressure to provide a solid residue. The solid was crystallized from 2B ethanol to give 1.25 g of N-[5-(1-ethyl-1-methylpropyl)-1,3,4-thiadiazol-2-yl]-2,6-diethylbenzamide. at reflux for sixteen hours cooled the solvent was removed by evaporation under reduced pressure to provide a solid residue The solid was crystallized from 2B ethanol

実験手順: 2,6-Diethylcyanobenzene was prepared by converting 2,6-diethylaniline to a diazonium salt and then reacting the diazonium salt with copper cyanide. Hydrolysis of 2,6-diethylcyanbenzene was effected by reaction with sodium hydroxide in ethylene glycol to provide 2,6-diethylaminocarbonyl benzene. The latter compound was reacted with phosphoric acid to provide 2,6-diethylbenzoic acid. Reaction of the benzoic acid with thionyl chloride afforded 2,6-diethylbenzoyl-chloride as an oil.
