R.sub.3 represents hydrogen, aralkyl radical containing 1 to 5 carbon atoms;
R.sub.2 represents hydrogen, an alkyl radical (optionally halogenated or substituted by a hydroxyl), a formyl radical, an acyl radical, a carbamoyl radical monosubstituted or disubstituted on the nitrogen;
R and R.sub.2 cannot both represent hydrogen;
