4’-Methylbiphenyl-2-carboxylic Acid is used in the synthesis of angiotensin II receptor antagonists used as potent orally active antihypertensives.
4′-Methyl-2-biphenylcarboxylic acid (4′-Methyl-bi-phenyl-2-carboxyl-ic acid) can be synthesized by reacting 4′-methylbiphenyl-2-carbonitrile with methanol and 30% NaOH solution. Its crystal structure has been characterized by the centrosymmetric hydrogen-bonded dimers.
Crystallise the acid from toluene or *C6H6 (m 147-148o). [Beilstein 9 H 677, 9 IV 2523.]
