Reaction Steps

A portion (0.53 g, 1.25 mmol) of the 1-[4-nitro-2-(1H-pyrrol-1-yl)phenoxy]-2-[N-(3,4-dimethoxyphenethyl)-N-methylamino]ethane produced in (3) above was dissolved in 50 ml of a 1:1 solvent system of ethyl acetate and methanol and 10% Pd/C (0.15 g) was slowly added to the solution, which was thereafter stirred at ordinary temperatures for 10 min as hydrogen gas was injected. Thereafter, the reaction mixture was filtered through Celite and the filtrate was evaporated, with the residue being purified by being subjected to column chromatography on silica gel using, as an eluent, ethyl acetate containing methanol (10%). The fractions containing the end product were combined and the solvent was evaporated to yield the end compound 1-[4-amino-2-(1H-pyrrol-1-yl)phenoxy]-2-[N-(3,4-dimethoxyphenethyl)-N-methylamino]ethane (0.49 g) as a yellow oil.
