Procedure

To a solution of EXAMPLE 107C (50 mg) in dichloroethane (3 ml) was added sodium triacetoxyborohydride (35 mg) and morpholine (15 mg). The mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate (200 ml) and washed with water, brine, and dried over Na2SO4. The residue was dissolved in tetrahydrofuran (4 ml), methanol (2 mL) and water (2 ml) and LiOH (100 mg) was added. The mixture was stirred at room temperature overnight. The mixture was concentrated and the residue neutralized with aqueous NH4Cl and extracted with ethyl acetate (100 mL×3). The combined extracts were dried and concentrated to give crude product, which was purified by RPHPLC. 1H NMR (300 MHz, dimethyl sulfoxide-d6) δ 8.25 (m, 1H), 7.86 (m, 2H), 7.45 (m, 9H), 6.93 (m, 2H), 4.99 (m, 2H), 4.47 (m, 1H), 4.25 (t, 2H), 3.60 (m, 10H), 2.43 (m, 2H), 1.92 (s, 3H).
