Reaction Steps

A solution of 3-[1-(2-hydroxy-ethyl)-5-nitro-1H-indol-2-yl]-3-methyl-butan-1-ol (300 mg, 1.03 mmol) and Raney Nickel (200 mg,) in CH3OH (30 mL) was stirred for 5 h at room temperature under a H2 atmosphere. The catalyst was filtered through a celite pad and the filtrate was evaporated under vacuum to give a residue, which was purified by preparative TLC to afford 3-[5-amino-1-(2-hydroxy-ethyl)-1 H-indol-2-yl]-3-methyl-butan-1-ol (70 mg, 26%). 1 H NMR (300 MHz, CDCl3) δ 7.07(d, J=8.7 Hz, 1 H), 6.83(d, J. 2.1 Hz, 1 H), 6.62(dd, J=2.1, 8.4 Hz, 1 H), 6.15(s, 1 H), 4.47(t, J=5.4 Hz, 2 H), 4.07(t, J=5.4 Hz, 2 H), 3.68(t, ./.5.7 Hz, 2H), 2.16(t, J. 5.7 Hz, 2 H), 4.00-3.91(m, 4 H), 2.76(s, 2 H), 1.61(s, 6 H), 1.42(s, 6 H).
