Reaction Steps

Following a procedure similar to that described in part B of Example 18 for interacting 3.24 g (0.01 mole) of 2-[(2-methyl-5-nitro-3-indolyl)carbonyl]benzoic acid, prepared as described in part A above, and 1.6 g (0.01 mole) of N,N,N',N'-tetramethyl-m-phenylenediamine in the presence of 5.0 ml of acetic anhydride, there is obtained 3-[2,4-bis(dimethylamino)phenyl]-3-(2-methyl-5-nitro-3-indolyl)phthalide (Formula III: R0 =R1 =R2 =R3 =R6 =H; R=R5 =CH3 ; R4 =N(CH3)2 ; Y1 =NO2).
