Abstract

The Specification describes compounds of the general formula <FORM:0928671/IV(a)/1> and salts thereof, wherein R is an alkyl group of 1 to 6 carbon atoms, R1 is methyl, ethyl, hydroxymethyl or hydroxyethyl or R and R1 together form a pyrrolidine or piperidine ring, and X is methyl, ethyl, or an alkoxy or substituted alkoxy group of 1 to 6 carbon atoms, or where R and R1 complete a ring, X may be hydrogen. They are prepared by oxidizing the corresponding N,N-disubstituted p-phenylene diamines with ferric chloride or potassium persulphate to replace the primary amino group by a hydroxyl group. Alternatively, they are prepared by alkylating or hydroxy alkylating the corresponding p-aminophenols, for example with ethyl bromide, ethylene chlorohydrin, 1;4-dibromobutane or 1;5-dibromopentane. In the case of the last two reagents, compounds wherein R and R1 together form a pyrrolidine or piperidine ring are formed. The comounds may be obtained in the form of their hemisulphates, hydrobromides or naphthalene 1;5-disulphonate salts.
