4-[benzyl(ethyl)amino]benzaldehyde

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Employing a procedure similar to that described in Example 1, part A above, for interacting 7.2 g of 4-(N-ethylbenzylamino)benzaldehyde and 5.2 g of 3-dimethylaminobenzoic acid, there was obtained 7.5 g of 3-4-(N-ethylbenzylamino)phenyl]-6-dimethylaminophthalide (Formula II: R=CH3 ; X=H; Y=(C6H5CH2)(C2H5)NC6H4) as a viscous oil.
