참여 물질

반응 단계

An excess solution of diazomethane in ether was added to an ice-cooled and stirred solution of o-chlorobenzoic acid (7.6 g, 48.6 mmol) in 50 ml of ether. After concentration, the residue was distilled under reduced pressure to give a colorless transparent oil of methyl o-chlorobenzoate (6.0 g, 35.2 mmol, yield 72.4%, b.p. 92°-93° C./7 mmHg), which was assigned the structure by the following data:
