Reaction Steps
The title compound was synthesized in analogy to 4-cyclopropyl benzaldehyde (described in example S53) using 1-bromo-4-(1-methoxycyclopropyl)-benzene (250 mg, 1.10 mmol), n-BuLi (722 μl, 1.6M solution in hexane, 1.16 mmol) and DMF (171 μl, 2.20 mmol). The isolated residue was purified by flash column chromatography (1:9 ether:pentane) to give 4-(1-methoxycyclopropyl)-benzaldehyde (90 mg, 58%) as a colorless oil. 1H NMR (CDCl3, 300 MHz): δ 10.0 (s, 1H), 7.79 (d, J=8.5 Hz, 2H), 7.37 (d, J=8.5 Hz, 2H), 3.29 (s, 3H), 1.35-1.30 (m, 2H), 1.09-1.05 (m, 2H).
