Process for preparing S-(2-aminoethyl)-2-methyl-L-cysteine |
| abstract |
The instant invention provides a process for the preparation of S-(2-aminoethyl)-2-methyl-L-cysteine comprised of the steps of (i) esterification of 2-methyl-L-cysteine; (ii) alkylation of the cysteine ester of step (i) to provide an N-protected S-(2-aminoethyl)-2-methyl-L-cysteine ester; and (iii) hydrolysis of the intermediate of step (ii) to provide the title compound in a salt free state. |
