(12 points) Synthesize the alikyne from the alkylbromide. More than one step is required. You may use any reagents you choose, but your answer should include any intermediate compounds produced as part of your synthesis. Remember to specify if your reagents for each transformation are stepwise use 1.2., etc) or if the reagents can be added all together. If you do not use 1. 2., etc, then I will assume you intend to use the reagents given all at once.
