Methyl 3-(4-bromophenyl)propanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: HCl in dioxane (4M, 61.1 mL) was added to a solution of 3-(4-bromophenyl)propanoic acid in methanol (60 mL) at room temperature. The reaction was stirred 18 h and then concentrated under vacuum. The crude product was purified by flash chromatography on silica gel using a 0-50% ethyl acetate-n-heptane gradient to afford 5.1 g of product as a colorless oil. concentrated under vacuum The crude product was purified by flash chromatography on silica gel using a 0-50% ethyl acetate-n-heptane gradient

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
