Abstract
There is provided a process for the production of a N-protected azetidine-2-carboxylic acid, which process comprises the steps of: (a) addition of base to an aqueous solvent comprising an organic acid addition salt of an azetidine-2-carboxylic acid; and (b) addition of protecting agent to the resultant reaction mixture.

A process for the production of a N-protected azetidine-2-carboxylic acid, which process comprises the steps of:
- (a) addition of base to an aqueous solvent comprising an organic acid addition salt of an azetidine-2-carboxylic acid;
- and (b) addition of protecting agent to the resultant reaction mixture.
A process as claimed in any one of the preceding claims, characterised in that the azetidine-2-carboxylic acid is azetidine-2-carboxylic acid.
A process as claimed in any one of the preceding claims, characterised in that the salt is L-azetidine-2-carboxylic acid-D-tartrate.
A process as claimed in any one of the preceding claims, characterised in that the protecting agent provides a tert-butyloxycarbonyl group.
