2-Methylbenzoyl chloride → HCID 66980798, compound

Participants

Reaction Steps

To 7-(2-ethylhexyl)-7H-benzo[c]carbazole (0.66 g, 2.00 mmol) in CH2Cl2 are added AlCl3 (0.27 g, 2.06 mmol) and 2,4,6-trimethylbenzoyl chloride (0.37 g, 2.00 mmol) at 0° C., and then the mixture is stirred for 2 hours. To the reaction mixture are added AlCl3 (0.29 g, 2.20 mmol) and o-toluoyl chloride (0.32 g, 2.06 mmol) at 0° C., and then the mixture is stirred overnight. The reaction mixture is poured into ice-water, and the crude product is extracted with CH2Cl2, and washed with water and brine. After drying over MgSO4 and concentration, the crude product is purified by column chromatography on silica gel eluting with a mixed solvent of CH2Cl2 and n-hexane (4:1) to obtain a white solid (0.25 g, 21%). The structure is confirmed by 1H-NMR spectrum (CDCl3) δ [ppm]: 0.84 (t), 0.93 (t), 1.22-1.45 (m), 2.04-2.09 (m), 2.18 (s), 2.38 (s), 2.39 (s), 4.32-4.34 (m), 6.97 (s), 7.30-7.37 (m), 7.42-7.47 (m), 7.51 (d), 7.68 (d), 7.88 (br), 7.96 (d), 8.21 (dd), 8.37 (d), 8.78 (br), 9.19 (br).
