Abstract

A novel glyoxal of the Formula I in which X is hydroxyl, alkoxy or NH 2 in the form of its hydrate may be prepared by oxidation of II where Z is hydrogen or halogen. The novel glyoxal may be converted to phenylethanolamines of the Formula VII where Y is hydroxyl or WNH, where W is an acyl, sulphonyl or carbamoyl group and R is a straight or branched chain alkyl, an aralkyl, aryloxyalkyl which may be substituted with one or more alkoxy or hydroxy groups or an adamantyl group by reaction of the glyoxal I with an amine RNH 2 to yield an azomethine III which may be reduced in one or two steps to VII (Y = OH) and in the case of X being NH 2 in I, reacting the amine group (Y = NH 2 ) with a functional derivative of an acid of the formula WOH to give VII (Y = WNH).
