A solution of 1-(2-cyclopent-1-enyl-2-oxo-ethyl)-2-methyl-pyridinium bromide salt (3.65 g, 12.9 mmol) in methanol (25 mL) was hydrogenated over 10% Pd/C (180 mg). After completion of the reaction the catalyst was removed by filtration, washing with methanol, and concentration of the filtrate gave 1-(2-cyclopentyl-2-oxo-ethyl)-2-methyl-pyridinium bromide salt (3.4 g, 93%).
