Reaction Steps

Using a method similar to Example 405, a reaction of 5-(4-formylphenoxy)pyridine-2-carboxamide (Example 388, Part D) (0.0366 g, 0.151 mmol) and 2-benzo[b]thiophen-3-ylethylamine (0.0295 g, 0.166 mmol) gives the title compound (0.0306 g, 50.2%): TOF MS ES+ 404.1 (M+H)+, HRMS calcd for C23H22N3O2S 404.1433 (M+H)+, found 404.1423, 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=8.9 min. 100% purity.
