- Process for preparing a hydroxyphenylglycine compound
-
Glyoxylic acid or a salt of glyoxylic, an ammonium salt of an organic or inorganic acid and a phenol compound of the formula: STR1 wherein n is an integer of one to three, are condensed together to prepare hydroxyphenylglycine compounds of the formula: STR2 wherein n is the same as defined above. The hydroxyphenylglycine compounds thus obtained are useful as intermediates in the synthesis of penicillins and cephalosporins.
