Reaction Steps

The N-carbobenzoxy-γ-aminobutyryl-taurine obtained as described in Example 2 is dissolved in 10 ml of water. 100 mg of 10% palladium-on-carbon catalyst are added to the solution, and the mixture is hydrogenated for 2 hours. The catalyst is filtered off, and the filtrate is evaporated in vacuo at 35° C. The obtained crude product is crystallized from a 1:10 mixture of water and acetone. 0.798 g (76%) of γ-aminobutyryl-taurine are obtained: m.p.: 247° C.
