The reaction was carried out with 4-hydroxy-1-indanone (125 mg) and iodomethane (263 μL) in the presence of potassium carbonate (350 mg) in N,N-dimethylformamide (DMF, 4 mL) for 3 h at 50 °C with stirring. After completion of the reaction, the mixture was poured into 1N hydrochloric acid (20 mL) and extracted with ether (4 × 10 mL). The organic layers were combined, dried with anhydrous magnesium sulfate, filtered and concentrated to give 4-methoxy-1-indanone intermediate as a clear oil (131 mg, 96% yield). Mass spectral analysis showed [MH]+ = 163.

Reaction Conditions:

with potassium carbonate in acetone at 60; for 5 h;

Steps:

1.1a (1a): Preparation of 4-methoxy-1-indanone
4-Hydroxy-1-indanone (2.00 g, 13.5 mmol), potassium carbonate (7.5 g, 54.0 mmol)Add to acetone (40 mL), add methyl iodide (3.8 g, 27.0 mmol), warm to 60 ° C and stir for 5 h.TLC showed the reaction was complete, cooled to room temperature and poured into water.It was extracted twice with ethyl acetate, and the organic phase was washed with brine.Dried over anhydrous sodium sulfate and concentrated to dryness.4-methoxy-1-indanone (2.18 g, yield 99%) was obtained.
