Reaction Steps

DL-3-amino-3-phenylpropionic acid (5.4 g, 0.032 moles) was added to saturated HCl (100 ml) in ethanol. The reaction mixture was stirred for 4 hours at room temperature under nitrogen. HCl in ethanol was removed under vacuum to afford a residue. The concentrated residue was trituated with ethyl acetate. The ethyl acetate was then removed in vacuum and the procedure was repeated twice. The resulting residue was dried under high vacuum to give a yellow solid (7.4 g, 98.6% yield). 1H NMR (400 MHz, CD3OD) δ 7.46-7.41 (m, 5H), 4.70 (m, 1H), 4.16-4.11 (m, 2H), 3.11-2.96 (m, 2H), 1.19 (t, 3H, 7.18 Hz). HRMS (M+H) calculated for C11H15N1O2 194.1176, found 194.1210.
