The correct sequence of reagents must be identified to achieve this transformation. The chosen sequence involves using NaNH2 and methyl chloride to initiate the reaction, followed by hydrogenation with H2/Pd-calcium carbonate, ozonolysis with O3/(CH3)2S, and finally, a reaction with Ba(OH)2 to yield the desired product."}
