Procedure

A sufficient quantity of ethanol to solubilize the product, and 15 mg of platinum oxide are added to 300 mg (0.953 mmoles) of 2-[3-(6-chloro-5-methyl -pyrimidin-4-yloxy)-propyl]-[1,8]naphthyridine. The reaction mixture is then purged under vacuum and surmounted on a balloon flask containing hydrogen. The reaction medium is left under stirring and at ambient temperature for 6 hours then overnight. The reaction mixture is then filtered on Clarcel and concentrated to dryness under reduced pressure (2 kPa). Then 300 mg of expected product is obtained.
