Procedure

20.7 mg (0.04 mmol) of rac-tert-Butyl 1-(3-{[cyclopent-1-en-1-yl(4-methoxypiperidin-1-yl)acetyl]amino}-4-fluorobenzyl)cyclopropanecarboxylate were initially charged in 3 ml of methanol, 3 mg (0.01 mmol) of platinum(IV) oxide were added and the mixture was hydrogenated at RT and standard pressure for 5 h. The mixture was then filtered through kieselguhr, the residue was washed thoroughly with methanol and the filtrate was concentrated under reduced pressure. 19.5 mg (100% purity, 94% of theory) of the title compound were obtained.
