Reaction Conditions

Reaction Steps

To a solution of Example 441 (100 mg, 0.2 mmol) in EtOH (4 mL) was added cyclohexene (1 mL) and palladium on carbon (120 mg, 10% wt). The reaction mixture was heated at 120° C. under microwave irradiation for 1 h. Additional palladium on carbon (40 mg, 10% wt) was added and the reaction mixture heated at 130° C. under microwave irradiation for 5 h. The reaction mixture was filtered through celite and concentrated in vacuo. Purification by preparative HPLC (Method 6) gave the title compound (12.5 mg, 12.5%) as a brown solid. δH (CDCl3) 8.11 (1H, d, J 2.4 Hz), 7.42 (1H, dd, J 8.1 and 7.3 Hz), 7.01 (1H, dd, J 8.9 and 2.4 Hz), 6.92 (1H, d, J 8.7 Hz), 6.68 (1H, d, J 7.9 Hz), 6.64 (1H, d, J 7.3 Hz), 6.42 (1H, br. s), 5.15 (1H, br. s), 4.26-4.38 (2H, m), 4.18-4.08 (2H, m), 3.76 (2H, t, J 6.8 Hz), 3.36 (3H, s), 2.94 (2H, t, J 6.8 Hz), 2.87 (2H, s), 1.39 (6H, s). LCMS (ES+) 466.18 (M+H)+, RT 2.17 minutes (Method 1).
