1-(4-Bromo-2-fluorophenyl)cyclopropane-1-carbonitrile → 1-Bromo-4-bromomethyl-5-fluoro-2-methoxy-benzene

Participants

Reaction Steps

The desired product was prepared analogously to Example A (141) step 1, substituting (4-Bromo-2-fluoro-5-methoxy-phenyl)-acetonitrile (1.95 g, 8.0 mmol) from step 3 below in place of 1-(4-bromo-2-fluoro-phenyl)-cyclopropanecarbonitrile. Yield: 2.45 g, 82.2%. 1H NMR (CDCl3) δ: 3.82 (s, 3H), 4.40 (s, 2H), 6.82 (d, J=5.8 Hz, 1H), 7.24 (d, J=10.58 Hz, 1H).
