Procedure
A solution of Example 510F (3.47 g, 8.87 mmol) in 100:1 methanol/concentrated HCl (152 mL) was added to 10% Pd/C (700 mg). The resulting suspension was reacted under 60 psi H2 at 50° C. for 16 hours and filtered. The filtrate was concentrated and purified by flash chromatography to provide Example 510G (methyl 2-{[(2-fluorophenyl)sulfonyl]amino}-5-methoxy-6,7,8,9-tetrahydro-5H-benzo[7]annulene-1-carboxylate) (1.16 g, 32%) and Example 510H (methyl 2-{[(2-fluorophenyl)sulfonyl]amino}-6,7,8,9-tetrahydro-5H-benzo[7]annulene-1-carboxylate) (1.05 g, 31%). Example 510G: MS (ESI(+)) m/e 408 (M+H)+, 425 (M+NH4)+; MS (ESI(−)) m/e 406 (M−H)−; 1H NMR (300 MHz, DMSO-d6) δ 10.00 (br s, 1H), 7.69 (m, 2H), 7.42 (t, 1H), 7.31 (t, 1H), 7.28 (d, 1H), 7.00 (d, 1H), 4.37 (d, 1H), 3.65 (s, 3H), 3.21 (s, 3H), 2.70 (m, 1H), 2.49 (m, 1H), 1.61 (m, 2H), 1.59 (m, 3H), 1.37 (m, 1H). Example 510H: MS (ESI(+)) m/e 378 (M+H)+, 395 (M+NH4)+, 400 (M+Na)+; MS (ESI(−)) m/e 376 (M−H)−; 1H NMR (300 MHz, DMSO-d6) δ 9.86 (br s, 1H), 7.61 (m, 2H), 7.35 (dd, 1H), 7.24 (td, 1H), 7.06 (d, 1H), 6.81 (d, 1H), 3.58 (s, 3H), 2.67 (t, 2H), 2.50 (m, 2H), 1.65 (m, 2H), 1.42 (m, 2H).
