Procedure

To a solution of 134d (200 mg, 0.30 mmol) in MeOH (20 mL) was added NaBH4 (40 mg, 0.9 mmol). The mixture was stirred at 20° C. for 2 h. After reaction it was evaporated and the residue was purified by reverse-phase prep-HPLC to afford 134 (108 mg, yield 54%) as a yellow solid. MS: (M+H)+ 655. 1H NMR (500 MHz, DMSO-d6) δ 8.61 (d, J=2.0, 1H), 8.49 (d, J=5.0, 1H), 8.43 (s, 1H), 7.85 (d, J=2.5, 1H), 7.45 (d, J=1.5, 1H), 7.37-7.39 (m, 1H), 7.35 (d, J=5.0, 1H), 7.24 (d, J=9.0, 1H), 4.99 (s, 1H), 4.56 (t, J=6.5, 2H), 4.40-4.47 (m, 4H), 4.18-4.22 (m, 2H), 4.05-4.09 (m, 1H), 3.84-3.96 (m, 1H), 3.60 (s, 3H), 3.41-3.46 (m, 1H), 3.07 (s, 4H), 2.54-2.61 (m, 2H), 2.39-2.42 (m, 6H), 1.78 (s, 2H), 1.69 (s, 2H)
