실험 절차

To benzyl 2-[(4-{[(3,4-dichlorophenyl)amino]carbonyl}piperazin-1-yl)methyl]-4-ethylpiperazine-1-carboxylate (20 mg) was added 4M HCl in dioxane (1 ml). The solvent was evaporated, 1-methyl-2-pyrrolidinone (1 ml), zinc bromide (10 mg) and 10% palladium on carbon (50 mg) added and the mixture stirred under hydrogen at RT for 72 hours. Evaporation to dryness and purification on a 10 g SCX2 column, eluting sequentially with ethyl acetate, MeOH and 1% ammonia/MeOH gave the title compound (9 mg, 60%) by precipitation from CH2Cl2 with isohexane.
