How will you bring about the following conversion in not more than two steps? Benzoic acid to m-Nitrobenzyl alcohol

Benzoic acid to m -Nitrobenzyl alcohol: In the conversion of Benzoic acid to m-Nitrobenzyl alcohol, the first step involved is the reduction of benzoic acid in the presence of LiAlH 4 followed by hydrolysis to give benzoyl alcohol. The product formed undergoes nitration by reacting with nitric acid in the presence of sulphuric acid to give m-Nitrobenzyl alcohol.
