실험 절차

Example 1 was repeated except that 32 g of 3-(3', 4'-dimethoxyphenyl)-6-dimethylaminophthalide and 13.5 g of 2-methylindole were used, respectively, instead of 30 g of 3-(p-dimethylaminophenyl)-6-dimethylaminophthalide and 13 g of dimethylaniline to obtain 33 g 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. ##STR11##
