sodiumsulphite, TBAB and protic solvent also works very good.
Sodium hypo sulphite (Na2S2O4) (2.5 Mol eq ) in methanol:water (5:1) at 35-40°C. Yield is pretty high.
You can try Nickel boride (Ni2B) - not a common reagent but very easy to try: dissolve nitro compound in protic solvent (i.e. methanol, water or a mixture thereof). Add NiCl2-6H2O (1.0 eq) followed by NaBH4 (10.0 eq). A black precipitate (the active Ni2B species) will rapidly form along with H2 (g) evolution. After stirring 30 minutes at RT check by TLC - if the reaction is not complete additional equivalents of NiCl2-6H2O and NaBH4 can be added. After complete reduction the mixture is filtered through celite and the solvent evaporated. The residue is partitioned between water and a suitable organic solvent (i.e. CH2Cl2). The aqueous layer is further extracted with CH2Cl2 and the combined organic layers washed with brine, dried over Na2SO4 and filtered. Solvent removal under vacuum yields the crude amine which can be further purified if necessary (i.e. by column chromatography). Good luck!
