Abstract

FIELD: organic synthesis. SUBSTANCE: method involves interaction of alkyl esters of 2-chlorobenzoic acid having common formula $$$ where $$$ with solution of phenyl lithium in diethyl ether. The process is carried out by cooling from minus 20 C to plus 20 C. Thus prepared (2-chlorophenyl)diphenyl methanol is obtained at 96 % yield. EFFECT: improved purity.
