No, because AlCl3 will be intract with CH2Br part. Other types of Lewis catalysts are probably not suitable for the same reason. You will need to change your strategy for the synthesis of 4-cyclopropylphenacyl bromide. Synthetic sequnce could be: Start from cyclopropylbenzene, the acetylation of the acetyl chloride / AlCl3 followed by the acetyl group monobromination by action of Br2 in HOAc.
Note: The reaction of phenacyl bromide with cyclopropyl- chloride (bromide, iodide) would produce an undesirable 3-cyclopropylphenyl derivative.
O.K. If you start by cyclopropyl-benzene you can use AlCl3 and chloroacetyl chloride. Cyclo propyl gp is a little-pit bulky. Thus column chromatography might be needed to isolate the minor ortho-product. By the way the product will be chloro instead of bromo.
It's better to use AlX3 of the same kind of X, because of possible halogen exchange.
