Procedure

In a round bottom flask, combine 4-(1-Oxo-indan-5-yloxy)-benzamide (Intermediate 24, 45.0 mg, 0.17 mmol), m-Fluorophenethylamine (33 uL, 0.25 mmol), THF (5 mL), and Ti(OiPr)4 (0.1 mL, 0.27 mmol) at 0° C. under nitrogen atmosphere. Stir the reaction for 3 hours then add TiCl4 (0.3 mL, 0.27 mmol) at 0° C. For the next 2 hours, warm the reaction to room temperature and then add BH3SMe2 (0.09 mL, 0.17 mmol). Stir the reaction at room temperature for 12 hours, then add 1N NaOH (aq) and stir for 2 hours. Centrifuge and decant the reaction into a separatory funnel and wash the organic phase with water and dry over Na2SO4. Concentrate the reaction under reduced pressure and purify using reverse phase chromatography (5% to 95% 0.001% TFA buffer in acetonitrile/water) to afford 3.8 mg, 0.01 mmol (6% yield) of the title compound:
