Reaction Steps

A mixture of EXAMPLE 8 (1.07 g, 3.5 mmol) and 10% palladium on carbon (0.2 g) in methanol (25 mL) was stirred overnight under 1 atmosphere of hydrogen and filtered. The filtrate was concentrated and the residue crystallized from methanol to provide the title compound (0.58 g, 60%). 1H NMR (DMSO-d6) δ 12.23 (s, 1H), 8.10-8.18 (m, 2H), 7.86-7.95 (m, 1H), 7.49 (t, J=7.0 Hz, 1H), 7.19 (s, 1H), 7.05-7.12 (m, 2H), 6.56-6.63 (m, 1H), 6.20 (s, 1H), 5.19 (s, 2H).
