실험 절차

Isobutylamine (50 mL, 0.5 mol) was cooled in an ice bath, and bromoacetic acid (6.1 g, 43.9 mmol) added slowly as a solid, insuring that each piece dissolved. After stirring overnight, the excess amine was removed and MeOH was added to the resulting oil. The resulting mixture was concentrated, and repeated using MeOH/HCl. Finally, a white solid was recrystallized from ethanol/ether to provide N-isobutylglycine.HCl (3.95 g, 53.7%).
