3-Methoxytoluene → (4-Bromophenyl)[2-methyl-4-(methyloxy)phenyl]methanone

Participants

Reaction Steps

To a mixture of 4-bromobenzoyl chloride (1.12 g, 5.12 mmol) and 3-methyl anisole (1.95 mL, 15.47 mmol) at 0° C. was added AlCl3 (0.83 g, 6.20 mmol). The mixture was allowed to warm to RT over 12 h with stirring. Water was added slowly, and the mixture was extracted with CH2Cl2. The organics were dried with MgSO4 and concentrated. The crude material was purified by chromatography on silica gel (EtOAc:hexanes) to yield 1.14 g (73%) of compound 27. 1H NMR (400 MHz, CDCl3): δ 2.41 (s, 3H), 3.86 (s, 3H), 6.74 (dd, J=2.5 Hz, 8.6 Hz, 1H), 6.82 (d, J=2.6 Hz, 1H), 7.31 (d, J=8.6 Hz, 1H), 7.58 (d, J=8.5 Hz, 2H), 7.62 (d, J=8.5 Hz, 2H).
