Reaction Steps

3.3 g (9.9 mmol) of N-benzyl-N-methyl-L-alanyl-D-lactic acid piperidide are hydrogenated in 100 ml of ethanol in the presence of 0.35 g of Pd(OH)2-carbon [20% Pd content] until absorption of hydrogen is complete (about 4 hours). After filtering off the catalyst, the entire reaction solution is concentrated in vacuo. 2.4 g (100% of theory) of N-methyl-L-alanyl-D-lactic acid piperidide are obtained.
