PROCEDURE

实验过程

A mixture of 173 mg of the product of Example 58 and 2 ml of a 33% solution of trimethylamine in ethanol was heated at 90° C. for 3 hours. The solvent was evaporated and the residue was purified on silica gel with dichloromethane/methanol/acetic acid/water (60:18:2:3). Trituration with ethyl acetate gave 75 mg of trimethyl [3-[3-[3-(1-methyl-3-indolyl)-2,5-dioxo-3-pyrrolin-4-yl]-1-indolyl]propyl]ammonium methylsulphonate, m.p. 180°-185° C.
