Versuchsvorschrift

The mixture of 5-cyclopentenyl-6-(cyclopropylmethoxy)-pyridine-2-carboxylic acid (0.95 g, 4 mmol), Pd/C (10% w/w, 0.2 g) in 30 mL of ethanol in a hydrogen atmosphere was stirred for 4 h at room temperature. The mixture was filtered and the filtrate was evaporated to dryness to obtain the product (0.76 g, 79%) as white solid. The product was directly used for the next step; MS (LC/MS): 262.1 [M+H]+.
