Procedure

A solution of Example 27G (1.00 g, 1.94 mmol) in tetrahydrofuran (40 mL) was treated with 10% palladium on carbon (0.100 g, 10% weight) and stirred at 25° C. under a hydrogen balloon for 72 hours. The vessel was purged with nitrogen gas and the mixture was filtered through celite. The filtrate was concentrated in vacuo to give the title compound (0.824 g, 99%). 1H NMR (300 MHz, DMSO-d6): δ ppm 0.54 (m, 1 H) 0.69 (m, 3 H) 0.86 (m, 1 H) 1.10 (m, 2 H) 1.56 (m, 3 H) 2.14 (m, 2 H) 7.18 (m, 2 H) 7.56 (m, 2 H) 7.76 (m, 2 H) 8.16 (m, 1 H) 10.40 (m, 1 H) 13.68 (m, 1 H). MS (ESI−) m/z 425 (M−H)−.
