Abstract

1361967 Pyrazine 4 oxide and derivatives thereof CARLO ERBA SpA 12 April 1972 [28 April 1972] 17645/73 Heading C2C The invention comprises compounds of the general formula wherein each of R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP>, which may be the same or different, is a hydrogen or halogen atom or a C 1 to C 6 alkyl or alkoxy group, at least one of R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> being other than a hydrogen atom; R<SP>4</SP> is a hydroxyl or C 1 to C 6 alkoxy group or a group of formula -NR<SP>5</SP>R<SP>6</SP> wherein each of R<SP>5</SP> and R<SP>6</SP>, which may be the same or different, is a hydrogen atom or a C 1 to C 6 alkyl group; or, when R<SP>4</SP> is a hydroxyl group, a pharmaceutically acceptable salt of said compound. The compounds can be prepared by oxidizing a compound of general formula wherein R<SP>1</SP> to R<SP>4</SP> are as defined above, and then if desired converting by methods know per se. The compound with the general formula of this invention so produced into another compound of the general formula of this invention and if desired, when R<SP>4</SP> is a hydroxyl group, reacting the compound of the general formula of the invention with a base to give a pharmaceutically acceptable salt. The oxidation is preferably performed with peracids, which may be prepared in situ. The preferred peracids are peracetic, m-chloro perbenzoic and permaleic acid. [GB1361967A]
