1,1'-(Chlorophenylmethylene)bis(4-methoxybenzene) → HCID 15546053, compound

Participants

Reaction Steps

To Compound 7 (140 mg, 0.53 mmol), anhydrous pyridine was added, followed by performing azeotropy of the mixture 3 times. Then, the product was converted into an anhydrous pyridine solution (1.5 ml), and 4,4′-dimethoxytrityl chloride (210 mg, 0.63 mmol) and DMAP (6.5 mg, 0.053 mmol) were added at room temperature in a stream of nitrogen. The mixture was stirred for 5 hours at room temperature. To the reaction mixture, a saturated sodium bicarbonate solution was added, followed by extraction with CH2Cl2. The organic phase was washed with water and a saturated sodium chloride solution, and then dried over anhydrous sodium sulfate. After the solvents were distilled off under reduced pressure, the resulting crude product was purified by silica gel column chromatography (CHCl3:MeOH=40:1) to obtain Compound 8 (230 mg, 0.34 mmol, 66%).
