Procedure
Thionyl chloride (10 ml) was added dropwise and cautiously to methanol (200 ml) with stirring. 4'-Amino-2'-methylbiphenyl-4-carboxylic acid (D26) (8.44 g, 37 mmol) was added, and the mixture was then stirred at reflux for 3 h. Solvent was then removed in vacuo to yield the title compound (9.16 g, 89%) as the hydrochloride salt.
