First we do diazotization of aniline to get a diazonium salt.
C6H5NH2+(NaNO2+HCl+H2O)(at 273 K) --> C6H5N2Cl (diazo salt)
Next at a warm temperature
C6H5N2Cl +(H3O+) ----> C6H5OH (phenol)

HEY THERE!
Here’s how to prepare Phenol from Aniline:
 
Aniline can be converted to phenol by converting it to a diazonium salt and hydrolysing with water.
 
When an aniline is treated with nitrous (NaNO2 + HCl) acid at 273 – 278 K, diazonium salts are obtained. These diazonium salts are highly reactive in nature. Upon warming with water, these diazonium salts finally hydrolyse to phenols. Phenols can also be obtained from diazonium salts by treating it with dilute acids.
 
 
Reactions:
C6H5NH2+(NaNO2+HCl+H2O)  (at 273 K) ---------> C6H5N2Cl 
C6H5N2Cl + H3O+ ------> C6H5OH (Phenol)
