For the conversion of 2,3- dibromobutane to 2- butyne following steps can be used

In this step, dehydrohalogenation occurs where 2,3 dibromobutane gets converted into 2- bromobut - 2-ene

In this step, also dehydrohalogenation occurs where alkenyl halide on treatment with soda amide gives 2- butyne
