Versuchsvorschrift
To a solution of 4-(5-fluoro-2-methoxyphenyl)-3,6-dihydro-2H-pyridine-1-carboxylic acid t-butyl ester (2.0 g, 6.5 mmol) produced in Example (106a) in methanol (30 mL) was added 10% palladium on carbon (0.99 g, wet), the mixture was stirred for 17 hours at atmospheric pressure and room temperature under a hydrogen atmosphere. The reaction mixture was filtered through Celite, and the obtained filtrate was concentrated under reduced pressure to give 2.0 g of the title compound as a light yellow oil.
