Reaction Steps

To a mixture of 3-(4-amino-phenyl)-propionic acid (1.00 g, 6.05 mmol) in 10 mL of methyl alcohol (MeOH) was added 0.80 mL of conc H2SO4. The resulting mixture was refluxed for 2 h, concentrated down to ca. half volume by distillation and then cooled to 45° C. Methyl tert-butyl ether (MTBE, 15 mL) was added. The mixture was allowed to cool to 0° C. and stirred for 0.5 h. The solid was collected by filtration and washed with 1:4 MeOH/MTBE (2×10 mL), MTBE (3×10 mL) and dried under reduced pressure. The title compound (1.43 g, 85%) was obtained as a white solid. 1H-NMR (DMSO-d6; 400 MHz): δ 8.40-11.0 (br s, 4H), 7.34 (d, 2H, J=8.2 Hz), 7.23 (d, 2H, J=8.2 Hz), 3.57 (s, 3H), 2.86 (t, 2H, J=7.4 Hz), 2.64 (t, 2H, J=7.4 Hz).
