Versuchsvorschrift

[4-(4-Fluoro-2-methyl-phenylethynyl)-pyridin-2-yl]-urea (25 mg, 0.093 mmol) is dissolved in methanol (1.0 mL) and DCM (1.0 mL). Then 5% palladium on carbon (20 mg, 0.0090 mmol) is added. The reaction is stirred for 16 hrs under the hydrogen atmosphere. The palladium on carbon is filtered and the filtrate is concentrated to give the crude product. Methanol (1 mL) is added into the crude and a white solid is formed. The solid is filtered, rinsed with more methanol and dried to give 18 mg of the titled product.
