• 2-ethylamino-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-phenethylamino-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-phenylamino-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-(p-bromophenylamino)-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-(p-chlorophenylamino)-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-(p-fluorophenylamino)-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-(m-fluorophenylamino)-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
• 2-(p-methoxyphenylamino)-5-(3-hydroxy-2-naphthyl)-1,3,4-thiadiazole
