Separation of the camphorsulfonic salts of the compounds of formula (I) and (II) by one or more crystallizations from a mixture of two solvents, both R(-)-10-camphorsulfonic acid and its salts with the compounds of formula (I) and (II) being well soluble in at least one of the components, the formula of which can be indicated as RaOH, wherein Ra is a straight or branched C1 to C5 alkyl. In the other components, camphorsulfonic acid and its salts are less soluble; however, they dissolve compounds of formula (I) and (II) very well.
