Reaction Conditions

Reaction Steps

To a solution of -(4-bromo-phenyl)-cyclopropanecarbonitrile from Step 1 in EtOH (0.2M) was added NaOH 25% (10 eq.). The mixture was stirred for 6 h at 100° C., quenched with AcOH (20 eq.), poured in brine, extracted with EtOAc (2×). The combined organic extracts were dried over MgSO4, filtered and concentrated. The residue was dissolved in CH2Cl2 and diazomethane was added portionwise until the esterification was completed by TLC. Flash chromatography (Hex:EtOAc; 9:1) afforded the title compound as a colorless oil.
