実験手順

A mixture of 3.22 g (0.01 mole) of 2-[(1-ethyl-2-methyl-3-indolyl)carbonyl]-5-aminobenzoic acid, 118 g (0.01 mole) of N,N,N',N'-tetramethyl-m-phenylenediamine in 10.0 ml of acetic anhydride was heated to 50° C. for one-half hour. After cooling to ambient temperature, 50 ml of water was added and the reaction mixture was filtered. The filtrate was rendered alkaline with dilute aqueous sodium hydroxide in the presence of 100 ml of toluene. The toluene layer was separated, dried and evaporated to obtain as tan crystals 3-[2,4-bis(dimethylamino)phenyl]-3-(1-ethyl-2-methyl-3-indolyl)-6-acetamidophthalide (Formula III: R0 =R1 =R3 =Y1 =H; R2 =NHCOCH3 ; R=R5 =CH3 ; R4 =N(CH3)2 ; R6 =CH2CH3) having a melting point of 204°-206° C. Infrared analyses showed maxima at 1733 cm-1 (C=O; s) and 1695 cm-1 (C=O; s). Nuclear magnetic resonance analysis was consistent with the structure. An acetone solution of the above compound developed an intense grape color when spotted on silica gel.
