Sodium Hydroxide → 5-(Pyrimidin-2-yl)pyridine-3-carboxylic acid

Participants

Reaction Steps

A 2 mol/L aqueous solution of sodium hydroxide (0.21 mL) was added to a solution mixture of the obtained methyl 5-(pyrimidin-2-yl)pyridine-3-carboxylate (30 mg) in dioxane (0.3 mL) and methanol (0.3 mL) at room temperature, followed by stirring at the same temperature for 1 hour and 30 minutes. The solvent was evaporated under reduced pressure, and water and toluene were added to the residue. The aqueous layer was separated and adjusted to a pH of 3.8 with 1 mol/L hydrochloric acid. The solid substance was collected by filtration to obtain 7.0 mg of 5-(pyrimidin-2-yl)pyridine-3-carboxylic acid as a white solid.
