The separation of rac‐o‐chloromandelic acid 1 with enantiopure aryloxypropylamine via diastereomeric salt formation was investigated. (R)‐o‐chloromandelic acid (R)‐1, a key intermediate for the antithrombotic agent clopidogrel, was obtained in 65% yield and 98% ee by Dutch resolution of rac‐1 with (S)‐2‐hydroxyl‐3‐(p‐chlorophenoxy) propylamine (S)‐5 as resolving agent and (S)‐2‐hydroxyl‐3‐(o‐nitrophenoxy)
