Reaction Steps

2.18 g of sodium 4-(2-benzenesulfonylaminoethyl)-2-nitrophenoxyacetate are dissolved in 50 ml of 80% methanol, and 0.44 g of 10% palladium-carbon is added thereto. After the mixture is subjected to catalytic hydrogenation for 3 hours at room temperature under atmospheric pressure, the catalyst is filtered off. The filtrate is condensed to dryness, and the residue is recrystallized from a mixture of isopropylether and water. 1.94 g of sodium 4-(2-benzenesulfonylaminoethyl)-2-aminophenoxyacetate are obtained as pale yellow scales.
