3-(2-Bromophenyl)propanoyl chloride

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: A mixture of 3-(2-bromophenyl)propanoic acid (prepared in 2 steps from 2-bromobenzyl bromide, 2.0 g, 8.73 mmole), oxalyl chloride (1.14 ml, 13.1 mmole) and methylene chloride (20 ml) was cooled in an ice bath and N,N-dimethylformamide (34 μL, 0.44 mmole) was added dropwise. The mixture was stirred at room temperature for 3 hours. Concentration in vacuo gave 3-(2-bromophenyl)propanoyl chloride which was taken up in methylene chloride and used in the next step as a crude. Step 2: was cooled in an ice bath Concentration in vacuo
