Reaction Steps

To 4-bromo-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine (1.98 g, 0.00605 mol) was added hydrazine (11.0 mL, 0.350 mol) followed by addition of methanol (1.0 mL, 0.025 mol) (to improve solubility). The reaction mixture was heated in a sealed tube at 97° C. (an oil bath) for 18 h. The reaction mixture was cooled to rt and formed an off-white solid precipitate. The solid was filtered off and rinsed with cold water and dried to give 4-hydrazino-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine (1.55 gm) as a light yellow solid, LC/MS (M+H)+:279, 1H NMR (DMSO-d6) δ 7.98(d, 1H), 7.91(s, 1H), 7.28(d, 1H), 6.69(s, 1H), 6.61(d, 1H), 5.58(s, 2H), 4.37(s, 2H), 3.56(t, 2H), 0.90(t, 2H), 0.0(s, 9H).
