Reaktionsschritte
To a solution of ester from step 1 in THF-MeOH (4:1, 0.5M) was added LiOH (3 eq, 2M) and the mixture was stirred at 50° C. for 1 h. The organic solvent evaporated, aqueous was acidified with HCl 1N and the acid extracted with EtOAc (3×). The organic was washed with brine, dried and solvent evaporated to afford 2-(4-bromophenyl)cyclopropanecarboxylic acid.
