## Abstract By a new procedure the resolution of DL‐3.4‐dihydroxyphenyl‐alanine into its optical antipodes is effected in good yield by means of fractional crystallization of the cinchonine salts of DL‐β‐(3‐hydroxy‐4‐methoxyphenyl)‐α‐benzoylaminopropionic acid. The well crystallized methylester‐hyd
