反応手順

A mixture of 0.46 g (1.35 mmol) of the ketoamine free base, N-[4-[2-(Dibutylamino)-1-oxoethyl]phenyl]methanesulfonamide, 0.15 g of 10% palladium on carbon catalyst and 150 ml of absolute EtOH is placed on a Parr hydrogenator and shaken under an hydrogen atmosphere for 18.5 hrs. The catalyst is removed by filtration and the filtrate is concentrated in vacuo. The residue is chromatographed on a 100 ml silica gel column (elution with 3% MeOH:CH2Cl2 containing 0.3% NH4OH) and fractions are collected. The title compound is recrystallized from Et2O:pet. ether.
