Participants

Reactant 2

HCID 6809Phthalimide

HCID 23668192Sodium Xylenesulfonate

Product 1

HCID 23681382Sodium 2-methylbenzenesulfonate

Procedure

The procedure of Example 2 was repeated using 30.6 grams Naxonate ST, a commercially available sodium toluene sulfonate from Ruetgers-Naese (0.15 mol sodium toluene sulfonate with a content of 93%) instead of phthalimide to yield a product in which toluene sulfonic acid methyl 6,13-dihydro quinacridone having a molecular weight of 500 was detected by MALDI.
