 Anisole on reaction with HCN + HCl in presence of AlCl3 followed by hydrolysis gives p-methoxy benzaldehyde( Gattermann Aldehyde synthesis)

HCN  +  HCl in presence of AlCl3  ..........>  HN=CHCl

C6H5OCH3  +  HN=CHCl in presence of AlCl3  ........>CH3O-C6H4-CH=NH(p)   hydrolysis with H2O  ......>                            CH3O-C6H4-CHO(p)
