2-(Bis(4-(dimethylamino)phenyl)methyl)-5-(dimethylamino)benzoic acid → Crystal Violet lactone

Participants

Reaction Steps

Employing a procedure similar to that described in Example 1, part C above, the potassium salt solution of 2-[4,4'-bis(dimethylamino)benzhydryl]-5-dimethylaminobenzoic acid from A was oxidized to obtain 3,3-bis(4-dimethylaminophenyl)-6-dimethylaminophthalide (Formula I: R=CH3 ; X=H; Y=Z=4-(CH3)2NC6H4) a tan-colored solid.
