Reaction Steps

4-(4-Ethylpiperazin-1-yl)-6-[4-(methoxymethoxy)phenyl]thieno[3,4-c]pyridine (695 mg) was dissolved in ethanol (10 ml), followed by the addition of a 5N aqueous solution of hydrochloric acid (1 ml) and the mixture was reacted for 1 hr with heating under reflux. The reaction solution was neutralized with a 1N aqueous solution of sodium hydroxide and then extracted with ethyl acetate. The organic layer was washed with brine, dried and evaporated, and then purified by silica gel column chromatography (dichloromethane/methanol system), to give 4-(4-ethylpiperazin-1-yl)-6-(4-hydroxyphenyl)thieno[3,4-c]pyridine as a yellow oil (70 mg, yield; 11%).
