Reaction Steps

To a solution of 0.24 g of tert-butyl (1-benzyl-2-methylpiperidin-4-yl)(2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)carbamate in 3 mL of methanol, 90 μL of acetic acid and 0.32 g of 20% palladium hydroxide were added. The reaction mixture was stirred for 4 hours 30 minutes under a hydrogen atmosphere. The insoluble substance was filtered off, and the solvent was distilled off under reduced pressure to obtain 0.16 g of tert-butyl (2,3-dihydro(1,4)dioxino(2,3-c)pyridin-7-ylmethyl)(2-methylpiperidin-4-yl)carbamate as a yellow foam.
