Participants

Reaction Steps

Using a method similar to Example 405, a reaction of 6-(4-formyl-2-methoxyphenoxy)nicotinamide (Example 414, Part B) (0.050 g, 0.184 mmol) and 2-(2-thienyl)ethylamine (0.0234 g, 0.184 mmol) gives the title compound (0.0495 g, 70.3%): TOF MS ES+384.1 (M+H)+, HRMS calcd for C20H22N3O3S 384.1382 (M+H)+, found 384.1375, 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=6.1 min, 100% purity.
