Reaction Steps

A solution of 3-(1H-imidazol-4-yl)-propionic acid (1.95 g, 13.9 mmol) and H2SO4 (catalytic) in MeOH (30 mL) was heated at reflux for 15 h, then concentrated in vacuo. The residue was dissolved in CH2Cl2 (40 mL) and washed with saturated NaHCO3(aq) (30 mL). The aqueous phase was saturated with sodium chloride and extracted with EtOAc (4×25 mL). The combined organic phases were dried (MgSO4) and concentrated in vacuo to give a yellow oil (1.93 g, 90%). 1H NMR (CDCl3) δ 2.68 (t, 2H, J=7.2 Hz), 2.93 (t, 2H, J=7.2 Hz), 3.69 (s, 3H), 6.81 (s, 1H), 7.55 (s, 1H).
