With trifluoroacetic acid; In dichloromethane;Inert atmosphere; | General procedure: 3-Iodo-4,5-dimethoxybenzaldehyde (1.5 mmol) and 2,4-dimethyl-3-ethylpyrrole (3.3 mmol) were dissolved in absolute CH2Cl2 (30 mL) under N2 atmosphere, 10 drops of TFA were added and the solution was stirred at rt overnight or until TLC analysis showed complete consumption of the aldehyde. At this time of DDQ (2.5 mmol) were added and stirring continued for 20 min. Then, Et3N (4 mL) and BF3·OEt2 (4 mL) were added. The mixture was stirred for 12 h then the organic layer containing the crude product was subsequently washed three times with water; the organic solution was dried over Na2SO4, and evaporated to dryness. The raw material was chromatographed (SiO2, petroleum ether/CH2Cl2, 6:4) affording 280 mg (yield: 33%) of 1a in the form of orange needles |
