Reaction Steps

To a clear yellow solution of 3-chloro-4-(2-nitro-1-((triethylsilyl)oxy)ethyl)quinoline (0.511 g, 1.39 mmol) in EtOH (7.96 mL) and water (1.99 mL) at room temperature was added iron powder (0.778 g, 13.9 mmol) and ammonium chloride (0.745 g, 13.9 mmol). The dark brown mixture was stirred and heated at 60° C. After 4 h, the mixture was cooled to room temperature and filtered through a celite pad and washed the pad with MeOH (3×30 mL). The combined filtrates were concentrated in vacuo. The residue was partitioned between EtOAc (100 mL) and water (50 mL). The mixture (pH ˜4.0) washed with saturated aqueous NaHCO3 (1×50 mL), water (1×50 mL), and brine (1×50 mL), dried over anhydrous Na2SO4, concentrated in vacuo, and dried under high vacuum to give 2-(3-chloroquinolin-4-yl)-2-((triethylsilyl)oxy)ethanamine (A275-6) as a yellow syrup. 1H NMR (400 MHz, DMSO-d6) δ 8.84 (1H, s), 8.72 (1H, d, J=8.2 Hz), 8.04 (1H, dd, J=8.4, 1.0 Hz), 7.76 (1H, ddd, J=8.4, 6.9, 1.4 Hz), 7.64 (1H, ddd, J=8.5, 7.0, 1.3 Hz), 5.52 (1H, dd, J=7.6, 5.5 Hz), 3.16 (1H, dd, J=13.0, 7.9 Hz), 2.88 (1H, dd, J=13.0, 5.4 Hz), 1.74 (1H, br. s.), 0.71-0.80 (1H, m), 0.71-0.80 (9H, m), 0.37-0.57 (6H, m); LCMS (ESI) m/z 337.1 (M+H)+.
