Procedure

To a solution of (vii) (127 mg, 0.34 mmol) in THF (2.5 mL) and MeOH (7.5 mL) was added Raney nickel (20 mg) and the reaction stirred vigorously under hydrogen atmosphere at 60° C. for 2 h. The reaction was diluted with MeOH (40 mL), filtered and then concentrated to dryness to give (viii) (97 mg, 83%). ESI-MS m/z calculated for [M+H]+: 341.1. found: 341.0. 1H NMR (400 MHz, d6-DMSO) δ 7.58-7.47 (m, 4H), 7.23 (s, 1H), 6.64 (m, 1H), 2.85-2.76 (m, 3H), 1.82-1.72 (m, 1H), 0.96-0.89 (m, 2H), 0.64-0.55 (m, 2H).
