Hydrochloric Acid → Methyl 5-bromo-2,3-dihydro-1H-indene-1-carboxylate

Participants

Reaction Steps

A solution of (rac)-5-bromo-indan-1-carboxylic acid (1.326 g, 5.5 mmol) in MeOH (55 ml) was treated with 4N HCl in dioxane (15 ml) and the mixture was stirred at reflux for 7 h. The yellow solution was allowed to cool to room temperature and all volatiles were removed. The remaining brown oil was purified by chromatography (silica gel; heptane/EtOAc 95:5) to obtain the title compound as light yellow oil (1.31 g, 93%).
