A problem with 1,8-diaminonaphthalene synthesis

Hi all,
I have a big problem with this reaction:

1,8-dinitronaphthalene > 1,8-diaminonaphthalene

I attempt to reduce the dinitro with HCl and Fe, but when I put inside NaOH
I have a precipitate like-black-green coloured (maybe Fe(OH)2) and a liquid
red/brown dark. I attempt to extract with CHCl3 and i had a red coloured
organic phase.
I hope somebody coul help me, because I don't know what's the problem but i
know 1,8-diamino it's a yellow solid and so i don't understand what's
happened in my beacher!
I need to synthetize the 1,8-diamino because it's an intermediate product to
have perylene.
Tank you in advance for any help and sorry for my terrible english!
