実験手順

Place 5-(2-fluoro-4-formylphenoxy)pyridine-2-carboxamide (Example 403, Part B) (0.650 g, 2.50 mmol), 2-fluorophenethylamine (0.382 g, 2.75 mmol) and 3 {acute over (Å)} molecular sieves in a vial. Add methanol (12 mL), cap and stir overnight. Add NaBH4 (slight excess) and stir until the gasses stop evolving. Load the reaction mixture directly onto a 25 g ISCO® pre-load column. Dry the column in a vacuum oven at room temperature. Purify by eluting through a 40 g ISCO® column with 0% to 10% (2.0 M NH3 in methanol) in ethyl acetate to give the title compound (0.718 g, 75%): TOF MS ES+ 384.2 (M+H)+, HRMS calcd for C21H20N3O2F2 387.2032 (M+H)+, found 387.2032, time 0.52 min; HPLC [YMC-Pro pack C-18 (150×4.6 mm, S-5 microm), 0.05% TFA/acetonitrile in 0.05% TFA/water at 1.0 mL/min, 10-20% over 5 min, 20-95% Over 18], tR=11.4 min, 100% purity.
