Procedure

Proceeding in a manner similar to that described in Example 1 above, 5.2 g of 2-(2-methyl-4-diethylaminophenyl)carbonylbenzoic acid, 1.2 ml of thionyl chloride and 5.0 ml of methyl alcohol were interacted in 30.0 ml of ethylene dichloride in the presence of 1.3 ml of pyridine to obtain 2.5 g of 3-methoxy-3-(2-methyl-4-diethylaminophenyl)phthalide (Formula II: R0 =R=R1 =R2 =H; R4 =R4' =C2H5 ; R5 =Y=CH3 ; X=O), a yellow-colored oil. A significant infrared maximum appeared at 1770 cm-1 (C=O;s). The nuclear magnetic resonance spectrum was concordant with the assigned structure. Analysis by mass spectrum showed m/e peaks at 325 (M+) and 294 (M+ -OCH3). A toluene solution of the product spotted on an acidic clay-coated paper developed a yellow-colored image.
