Procedure

Example 1 was repeated except that 32g of 3-(3', 4'-dimethoxyphenyl)-6-dimethylaminophthalide and 13.5 g of 2-methylindole were used, respectively, instead of 30g of 3-(p-dimethylaminophenyl)-6-dimethylaminophthalide and 13g of dimethylaniline to obtain 33g of triarylmethane having the following structure whose m.p. was 230°-232° C in the form of colourless crystals (Recrystallized from methanol). This compound becomes bluish violet upon exposure to light on silica gel. ##STR10##
