Synthesis of bromobutane

What will be the cost efficient and high yielding method of synthesis for 1-bromobutane?

I can react butanol with $\ce{HBr}$ but I am worried butanol is not present at the moment in lab. But I need to hurry and make bromobutane.

• Well, clearly what you do have in the lab will the rate determining step. What potential candidates have you got in the inventory? – long May 14 '15 at 5:36

On a technical scale, one would probably react 1-butene with anhydrous hydrogen bromide under radical conditions, using peroxides or UV light to initiate homolytic cleavage of the $\ce{H-Br}$ bond.
