To a mixture of (3,4-dinitro-phenyl)-morpholin-4-yl-methanone (2.84 g) in dry THF (50 ml) was added NaBH4 (954 mg) followed drop-wise by BF3.Et2O (3.2 ml). The mixture was stirred at ambient temperature for 3 hours and then quenched though addition of MeOH. The mixture was reduced in vacuo, partitioned between EtOAc and water and the organic portion washed with brine, dried (MgSO4) and reduced in vacuo. The residue was purified via flash column chromatography eluting with EtOAc to give 4-(3,4-dinitro-benzyl)-morpholine (1.08 g).
