Reaction Steps

Using a method similar to Example 405, using 5-(2-fluoro-4-formylphenoxy)pyridine-2-carboxamide (Example 403, Part B) (0.040 g, 0.154 mmol) and 2-(2-thienyl)ethylamine (0.0196 g, 0.154 mmol) gives the title compound (0.03444 g, 60.2%): TOF MS ES+ 372.1 (M+H)+, HRMS calcd for C19H19N3O2FS 372.1182 (M+H)+, found 372.1168, time 0.39 min; HPLC [YMC-Pack Pro C-18 (150×4.6 mm, S-5 microm), 0.1% TFA/acetonitrile in 0.1% TFA/water at 1.0 mL/min, 20-99% over 23 min], tR=6.9 min, 100% purity.
