I'm making Esters of amino acids like, L-alanine methyl/t-butyl/benzyl ester but have process of making their Hydrochloride salts thro' amino acid, the alcohol & thionyl chloride & reflux.

Thro' this, I'm getting their HCl salts. But I want only the respective esters NOT as their hydrochlorides. I can not do the amine liberation by making it alkaline with NaOH/NH3, etc.

Can you suggest me making only the Aminoacid Esters thro' some process ?

Thanks,
Kamal
