Abstract:
The present invention relates to the hemi sulfuric acid salt of methyl (R)-2-amino-2-(cyclohexa-1,4-dien-1-yl)acetate, also trivially referred to as the hemi sulfuric acid salt of D-dihydrophenylglycine methyl ester, to a method for the preparation of said salt and to the use of said salt in the enzymatic synthesis of antibiotics.

Claim (Index 5):
Method for the preparation of the hemi sulfuric acid salt of methyl (R)-2-amino-2-(cyclohexa-1,4-dien-1-yl)acetate comprising the steps of:\n (a) contacting methyl (R)-2-amino-2-(cyclohexa-1,4-dien-1-yl)acetate free base with sulfuric acid; (b) isolating the hemi sulfuric acid salt of methyl (R)-2-amino-2-(cyclohexa-1,4-dien-1-yl)acetate from the mixture obtained in step (a), characterized in that in step (a) the molar amount of sulfuric acid is from 0.4 to 0.6 relative to the molar amount of methyl (R)-2-amino-2-(cyclohexa-1,4-dien-1-yl)acetate.
