How will you convert the following ? Aniline to Flourobenzene

Fluoroarenes are formed by treating freshly prepared diazonium salt solution with fluoroboric acid dissolved in corresponding halogen acids. This reaction is known as the Balz-Schiemann reaction. Aniline is first treated at an ice-cooled temperature in excess of hydrochloric acid with sodium nitrate to form benzene diazonium chloride. Therefore, the following reaction will take place to obtain fluorobenzene from aniline and producing diazonium fluoroborate as an intermediate.
