Reaction Steps
To 4-methoxy-1-indanone (0.1 g; 0.62 mmol) were added thiophene-2-carboxaldehyde (87.5 μl ; 0.93 mmol), piperidine (18.5 μl ; 0.18 mmol) and acetic acid (10.7 μl ; 0.18 mmol). After heating at 130° C. for 90 minutes the mixture was taken up in CH2Cl2, washed with water and purified by flash chromatography, eluting with petroleum ether/ethyl acetate (95/5) to give 4-methoxy-2-(2-thienylmethylene)-1-indanone (140 mg; 90%).
