Hi, Reduction of nitrile
 
 You may want to try the following method: " Transfer hydrogenation of nitriles with 2-propanol and Raney Nickel" Synthetic Communication 2003 33(19) 3373-3379, the concentration of hydrogen is lower, maybe your halo don't knock out.
 
Good luck

Dear all
I m having difficulty in reducing aromatic cyano group when it is substituted with 2-halo group(2-chlorobenzonitrile) . I have tried LAH & Raney Ni but in vain because in that case the reaction was going but NMR showed that my halo was getting knocked out & the mass was also showing same thing .
Do any body have any idea or referances regarding this ?
It will be very help full to me.
