Ethyl{7-[5-(2-methyl-propenyl)pyridin-2-yl]-7-azaspiro[3.5]non-2-yl}carbamate → Ethyl[7-(5-isobutylpyridin-2-yl)-7-azaspiro[3.5]non-2-yl]carbamate

Participants

Reaction Steps

0.05 g (0.45 mmol) of palladium-on-charcoal is added to a solution of 0.37 g (1.08 mmol) of ethyl{7-[5-(2-methylpropenyl)pyridin-2-yl]-7-azaspiro[3.5]non-2-yl}carbamate obtained in the preceding step, in 15 mL of methanol. The reaction medium is placed in a Parr flask under a hydrogen atmosphere (10 psi) at room temperature for 2 hours. The resulting mixture is filtered through a Büchner funnel and the filtrate is then concentrated under reduced pressure. 0.37 g of expected product is thus obtained in the form of a yellow wax.
