The condensation of the isoquinoline intermediate (IX) with the naphthaleneboronic acid intermediate (XIX) by means of palladium tetrakis(triphenylphosphine) and NaHCO3 in refluxing ethanol/toluene gives a 5:4 mixture of the (S) and (R) atropaisomers (XXIII), which, without separation, is submitted to debenzylation by means of H2 over Pd/C in methanol/dichloromethane affording a mixture of the target (S-biar) compound, along with its (R-biar)-atropaisomer that are separated by HPLC.
