Reaction Steps

The title compound was synthesized in analogy to 4-cyclopropyl benzaldehyde (described in example S1-A) using 2.07 g of 1-bromo-4-cyclopentyl-benzene (9.2 mmol), 6.32 ml of a 1.6 molar solution of n-BuLi in hexane (10.11 mmol) and 1.422 ml of DMF (18.4 mmol). 4-Cyclopentyl-benzaldehyde was isolated by flash column chromatography (5:95 EtOAc/c-hexane) as a colorless liquid (1146 mg, 72%). 1H NMR (CDCl3, 300 MHz): δ 1.53-1.91 (m, 6H), 2.11 (m, 2H), 3.07 (quint, J=8.5 Hz, 1H), 7.40 (d, J=8 Hz, 2H), 7.80 (d, J=8 Hz, 2H), 9.97 (s, 1H).
