Fischer esterification of 4'-hydroxybiphenyl-4-carboxylic acid (I) with H2SO4/MeOH provides ester (II). The phenolic hydroxyl group is then alkylated with 1-bromo-3-chloropropane (III) in the presence of K2CO3 to furnish the chloropropyl ether (IV). Saponification of methyl ester (IV) with LiOH leads to carboxylic acid (V), which is further activated as the corresponding acid chloride (VI) upon heating in SOCl2. Acid chloride (VI) is subsequently coupled with morpholine (VII) to yield amide (VIII). Finally, alkyl chloride (VIII) is displaced with (R,R)-2,5-dimethylpyrrolidine (IX) in the presence of K2CO3 and KI to furnish the title compound.
