    • N-(2-Mercaptoethyl)aminomethyl polystyrene resin could be regenerated by agitating it with three 25 mL portions of 25% piperidine in DMF on a glass fritted funnel for 10 min per cycle followed by filtration. Minimal fluorescence was released after the third wash as seen by TLC under a handheld long wavelength UV lamp. The resin was rinsed 2×DMF, 3×MeOH, and dried under vacuum
