Reaction Steps

A solution of 99 (0.070 g, 0.29 mmol) in AcOH/MeOH was stirred under an atmosphere of H2 in the presence of 10% Pd/C. After TLC analysis indicated reaction was over, the reaction was filtered through Celite, concentrated and chromatographed on silica gel (MeOH/CH2Cl2 1:9) to yield 25 mg of the desired product: Mp=251-254° C.; 1H NMR (DMSO-d6) δ 9.76 (br s, 1 H), 8.65 (br s, 1 H), 7.71 (d, 2 H, J=8.5 Hz), 6.86 (s, 1 H), 6.84 (d, 2 H, J=8.7 Hz), 6.09 (d, 1 H, J=1.9 Hz), 6.02 (d, 1 H, J=1.9 Hz), 5.21 (s, 2 H); MS 242 (M+H)+.
