1,3-Dibromopropane → 5-(3-Bromo-propoxy)-6-methoxy-indan-1-one

Participants

Reaction Steps

A mixture of 5-Hydroxy-6-methoxy-indan-1-one (Intermediate H) (5.0 g, 0.028 mole), 1,3-dibromopropane (5.7 mL, 0.056 mole) and sodium hydride (1.2 g, 0.028 mole) were stirred in 50 mL of DMF at room temperature overnight under Argon. The reaction mixture was quenched with water (150 mL), extracted with ethyl acetate, then washed with 1 N HCl and brine. The extract was dried over sodium sulfate and the solvent removed in vacuo to yield the title compound, 5-(3-Bromo-propoxy)-6-methoxy-indan-1-one. MS m/z 297 (M+H)+.
