Hydrochloric Acid → methyl 3-(3-(3-(hydroxymethyl)pyridin-2-yl)-1H-pyrazol-1-yl)propanoate

Participants

Reaction Steps

To methyl 3-(3-(3-((tert-butyldimethylsilyloxy)methyl)pyridin-2-yl)-1H-pyrazol-1-yl)propanoate in MeOH (10 mL) was added HCl (2 N, 1.2 mL, 10 eq.). The mixture was stirred at rt for 4 h, concentrated, neutralized to pH 7-8 with NaHCO3(sat) solution, and extracted with EtOAc three times. The combined organic layers were washed with brine, dried over Na2SO4, concentrated, and purified on silica gel using EtOAc as eluent to give methyl 3-(3-(3-(hydroxymethyl)pyridin-2-yl)-1H-pyrazol-1-yl)propanoate (51 mg, 67%) as an oil. LRMS (M+H+) m/z 262.1.
