Reaction Steps

A mixture of 5,7-difluoro-1,2,3,4-tetrahydronaphthalen-2-ylamine (6.0 g, 32.8 mmol), prepared as in Example 8, and ethyl glyoxylate (4.6 g, 36.0 mmol) in 300 mL of ethanol was hydrogenated over 10% palladium on carbon (0.75 g) for 10 hours. The mixture was filtered and concentrated by evaporation. Purification of the residue by column chromatography on silica gel (elution: 30% ethyl acetate/hexane) gave ethyl [(5,7-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino]acetate (7.5 g, 27.9 mmol) as an oil.
