Example Methylcyclopentane TM

While this cyclization reaction offers a good method for the formation of five-membered rings, the required starting material is nearly as complex as the desired TM and is unlikely to be commercially available. Therefore, the use of this synthetic strategy is likely to require the synthesis of the alkenyl halide starting material. A retrosynthetic analysis of the alkenyl halide can begin with either functional group. 

Provide the reagents necessary to transform the given starting material into the desired product.
