实验步骤: Place 5-(2-fluoro-4-formylphenoxy)pyridine-2-carboxamide (Example 403, Part B) (0.650 g, 2.50 mmol), 2-thiomorpholin-4-ylethylamine (0.402 g, 2.75 mmol) and 3 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 30% (2.0 M NH3 in methanol) in ethyl acetate to give the title compound (0.792 g, 81%): TOF MS ES+ 391.2 (M+H)+, HRMS calcd for C19H24N4O2FS 391.1604 (M+H)+, found 391.1594, time 0.48 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=6.7 min, 100% purity. Dry the column in a vacuum oven at room temperature Purify by eluting through a 40 g ISCO® column with 0% to 30% (2.0 M NH3 in methanol) in ethyl acetate
