To a solution of 1-(2-methoxyacetyl)-7-nitro-1,2,3,4-tetrahydroquinoline (D6) (212 mg, 0.85 mmol) in dry THF (9 ml) at 0° C. under an argon atmosphere, was added borane/THF complex (4.5 ml, 4.5 mmol). The reaction was stirred at 0° C. for 0.5 h then ambient temperature for 3 h. 2M Hydrochloric acid (3 ml) was added cautiously followed by water (10 ml). The mixture was extracted with EtOAc (2×10 ml) which was dried over MgSO4 and concentrated in vacuo to give the desired product as an orange solid in quantitative yield. 1H NMR (250 MHz, CDCl3) δ (ppm): 7.39 (m, 2H), 7.00 (m, 1H), 3.61 (dd, 2H), 3.52 (dd. 2H), 3.41 (m, 2H), 3.37 (s, 3H), 2.80 (t, 2H), 1.95 (m, 2H).
