실험 절차

A mixture of 3.35 g (0.01 mole) of 2-[(1-n-butyl-2-methyl-3-indolyl)carbonyl]benzoic acid, prepared as described in part A above, 1.80 g (0.011 mole) of N,N,N',N'-tetramethyl-m-phenylenediamine and five ml of acetic anhydride was stirred at ambient temperature for a period of approximately 18 hours. The reaction mixture was then poured into a mixture of 40 ml of water, 40 ml of ligroin and 20 ml of 10 percent aqueous sodium hydroxide. The ligroin layer was separated and the white crystals which separated from the solution on standing, were collected by filtration and dried to obtain 3-[2,4-bis(dimethylamino)phenyl]-3-(1-n-butyl-2-methyl-3-indolyl)phthalide (Formula III: R0 =R1 =R2 =R3 =Y1 =H; R=R5 =CH3 ; R4 =N(CH3)2 ; R6 =(CH2)3CH3) which melted at 165°-167° C. A characteristic infrared maximum appeared at 1752 cm-1 (C=O; s). A toluene solution of the product spotted on silica gel developed an intense purple-colored image.
