Reaction Steps

A solution of compound 127 (0.2 g, 0.518 mmol) in dry MeOH (3 mL) was treated with Ra—Ni (0.02 g) followed by hydrazine hydrate (0.16 mL, 5.188 mmol) at room temperature. The reaction was placed in a pre-heated oil bath and refluxed for 2 min. The reaction brought to room temperature, filtered through celite bed and washed with methanol (2×15 mL). The solvent was evaporated and crude was purified by column chromatography (2M NH3 in MeOH:CH2Cl2, 2.5:97.5) to obtain compound 130 as a foam. 1H NMR (DMSO-d6) δ 1.08 (t, 3H, J=6.9 Hz), 1.41 (s, 9H), 1.72-1.89 (m, 2H), 2.18-2.60 (m, 4H), 3.10-3.20 (m, 2H), 4.01 (brs, 1H), 4.71 (s, 2H), 6.02 (brs, 1H), 6.39 (dd, 1H, J=1.5, 8.5 Hz), 6.51 (d, 1H, J=1.8 Hz), 6.99 (d, 1H, J=2.1 Hz), 7.43 (d, 1H, J=8.4 Hz), 10.44 (s, 1H); ESI-MS (m/z, %): 378 (M+Na, 8), 356 (MH+,4), 300 (100).
