## Abstract The synthesis of the new chiral ligand (3,5‐di‐__tert__butylpyrazol‐1‐yl)(3′,5′‐dimethylpyrazol‐1‐yl)aceticacid (bpaH^__t__^^Bu2,Me2^) (4) has been achieved. Two different synthetic routes to its precursor 3,5‐di‐__tert__‐butyl‐1‐[(3,5‐dimethyl‐1__H__‐pyrazol‐1‐yl)methyl]‐1__H__‐pyrazol
