| Synthesised by cyclohexanone, malononitrile and sulfur with a yield of 91%,2 - amino-3 - cyano-4,5,6,7 - tetrahydro - benzothiophene was then to form the key intermediate of 4 - chloro-2 - (trifluoromethyl) -5,6,7,8 - tetrahydro-benzo [4,5] thieno [2,3 - -d] pyrimidine by reacting with trifluoroacetic acid and phosphorus oxychloride synthesized with 70% yield and, finally,the three unreported compound with 2 - amino-1, 3,4 - thiadiazole derivatives. The structure of the target compounds were characterized by IR and MS . |
