  • Methyl ester hydrochlorides of amino acids can be conveniently prepared with excess reagent in combination with conc. HCl. Water is removed in situ, thus displacing the equilibrium in favor of the ester: J. Org. Chem., 28, 3898 (1963). Methyl esters of non-aromatic acids can also be prepared with the reagent in MeOH with a catalytic amount of HCl or TMS chloride: Tetrahedron Lett., 38, 2685 (1997).
