Abstract

1301492 Pyrazoline and benzopyrazine derivatives BAYER AG 4 Sept 1970 [5 Sept 1969] 42473/70 Heading C2C [Also in Division C4] Compounds of the formula.- wherein R 1 and R 2 are H; R 3 and R 4 are H or phenyl and R-(CH = CH) m -, wherein m is 0 or 1, is 4-methoxyphenyl, 4-ethoxyphenyl, 4- methylphenyl, 4-ethylphenyl, 4-biphenylyl, 3- methoxyphenyl, 3,5-dimethylphenyl, 4-chlorophenyl, 3,4-dichlorophenyl, 4-bromophenyl, 4- cyanophenyl, 4-fluorophenyl, 4-trifluoromethylphenyl, 4-methylsulphonylphenyl, 4-methylsulphonylaminophenyl, styryl, 4-chlorostyryl and thienyl are prepared by methods analagous to the following which is used for the production of the compound in which R is 4-methoxyphenyl:- The Mannich base obtained from 4-methoxyacetophenone, paraformaldehyde and dimethylamine is heated with hydrazine hydrate in methanol/NaOH. The aldehyde of formula is prepared by heating o-chloronitrobenzene with excess n-propylamine and copper powder, the nitro N-propyl aniline formed is reduced and reacted with pyruvic acid to give this compound is methylated with dimethyl sulphate and treated with Na 2 CO 3 solution to give the methylene base which is converted to the aldehyde by the Vilsmeier reaction. Other aldehydes of formula wherein R 8 is methyl or ethyl, R 9 is alkyl 1-6C, cyclohexyl, phenalkyl or phenyl and the benzene ring is substituted by methyl, methoxy, ethoxy or chloro are prepared by analagous methods.
