Methanol → Methyl 3-(1H-Imidazol-5-Yl)Propanoate

Participants

Reaction Steps

Add thionyl chloride (0.75 mL) to a −78° C. solution of 3-(1H-imidazol-5-yl)propanoic acid (2.0 g; 1.0 equiv; 14.27 mmoles) in methanol (18 mL). Allow the reaction mixture to warm to ambient temperature and stir for 30 minutes. Add saturated sodium bicarbonate (10 mL) to the reaction mixture and concentrate. Suspended the resulting residue in methanol (10 mL) and filter, then concentrate to afford methyl 3-(1H-imidazol-5-yl)propanoate (2.2 g; 100%) as a white solid: MS (m/z): 155(M+1).
