    Abstract: Thiazoloquinazoline derivs. of formula (I): (where n is 4, 5, 6 or 7; and R' and R2 are H, halogen, lower alkyl, OH, alkoxy, NO2, NH2 or SO3H). Bactericides and fungicides. Also anti-inflammatories, analgesics and sedatives. EXAMPLE A mixture of o-isothiocyanatobenzoic acid methyl ester (5.8 g), 1-ethynyl-cyclohexylamine (3.7 g) and n-PrOH (50 ml) is stirred 1 hr. at room temp., refluxed 2 hrs., cooled, treated with KOH (0.3 g) in H2O (1 ml), refluxed 2 hrs., and evapd. The residue is taken up in CH2Cl2 and the soln. is washed with dilute HCl and water, dried (Na2SO4) and evapd. The residue (8.5 g) is recrystallized from EtOH (charcoal) to give 2-methylene-3-spirocyclohexan-2,3-dihydro-5-oxo-5H-thiazolo- 2,3-- b quinazoline (6.4 g), m.pt. 119-120 degrees.

    Abstract: Process comprises reacting a cpd. (I) with a cpd. (II) and cyclising the resulting cpd. (III) to give the 2-methylene-2,3-dihydro-5-oxo- 5H-thiazolo-[21,31-b]quinazoline (IV): (where R1, R2, R3 are H or aliphatic gp., or R3 may be halogen, OH, CF3, alkoxy, alkylthio, NO2, CN, carboxyamido, sulphonic acid gp. or -NR4R4 where each R4 is H or aliphatic gp.). Cpds. (IV) are inflammation preventing agents, analgesics and sedatives, fungicides, bactericides and inters. for pharmaceuticals, dyes and pesticides.

    Abstract: 1494757 1,3,4-Thiadiazolium compounds BASF AG 20 Feb 1975 [21 Feb 1974] 7106/75 Heading C2C The invention comprises novel compounds (I) in which (a) R 2 , R 3 , R 4 , R 5 and R 6 are identical or different and are hydrogen, fluorine, chlorine, bromine, iodine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms in the alkyl moiety, trifluoromethyl or NO 2 , at least one of the substituents R 2 to R 6 being different from hydrogen, and R 1 is alkyl or 2 to 6 carbon atoms which is optionally substituted by OH, CN, phenyl or cycloalkyl of 3 to 6 carbon atoms in the ring, or (b) R 1 is methyl optionally substituted by phenyl or cycloalkyl of 3 to 6 carbon atoms in the ring when at least two of R 2 to R 6 are different from hydrogen, or, when R 2 , R 3 , R 5 and R 6 have the above meanings, R 4 is hydrogen, fluorine, bromine, iodine, alkyl of 2 to 4 carbon atoms, alkoxy of 2 to 4 carbon atoms in the alkyl moiety, trifluoromethyl or NO 2 and at least one of R 2 , R 3 , R 4 , R 6 and R 6 is different from H, or (c) R 2 , R 3 , R 4 , R 5 and R 6 are each hydrogen when R 1 is alkyl of 3 to 6 carbon atoms which is optionally substituted by OH, CN, phenyl or cycloalkyl of 3 to 6 carbon atoms in the ring or when R 1 is ethyl which is #-substituted by OH, CN, phenyl or cycloalkyl of 3 to 6 carbon atoms in the ring, or (d) R 1 is methyl substituted by cycloalkyl of 3 to 6 carbon atoms in the ring when R 2 , R 3 , R 4 , R 5 and R 6 are each hydrogen or R 2 , R 3 , R 5 and R 6 are hydrogen and R 4 is chlorine. They are made by reacting compounds (II) (obtained by reacting compounds III with R 1 NHNH 2 ; the free acids corresponding to III are also prepared as are compounds IV) with carbon disulphide or thiophosgene. Pharmaceutical preparations having anticonvulsive action contain (I) as active ingredient. Administration is preferably orally.
