Water → 2-(4-Chlorophenyl)cyclopropanecarboxylic acid

Participants

Reaction Steps

A mixture of 2-(4-chloro-phenyl)-cyclopropanecarboxylic acid methoxy-methyl-amide (9.6 g), water (20 mL), and NaOH (3.2 g) in MeOH (40 mL) was refluxed for 3 h. The reaction mixture was cooled down to room temperature and concentrated in vacuo. The residue was acidified by 6 N HCl followed by extraction with CH2Cl2. The organic layer was washed with brine, dried over MgSO4 and concentrated in vacuo to give the title compound (7.3 g).
