Reaction Steps
A solution of 0.275 g of 2-methyl-2-pyridin-2-yl-propionic acid methyl ester [CAS 476429-22-8] in 10 ml of methanol at room temperature is admixed with 3.65 ml of 1M aqueous lithium hydroxide solution. After stirring for 12 hours, the reaction mixture is adjusted to pH 6-7 with 1M HCl and concentrated by evaporation. The residue is dissolved in 60 ml of 5:1 ethyl acetate/methanol, dried over sodium sulphate and concentrated by evaporation to provide the crude title compound as a yellow solid which is used without further purification.
