1,1-Dimethylethyl 10-(phenylmethyl)-3,10-diazabicyclo[4.3.1]decane-3-carboxylate → tert-butyl 3,10-diazabicyclo[4.3.1]decane-3-carboxylate

Participants

Reaction Steps

A solution of 10-benzyl-3-Boc-3,10-diazabicyclo-[4.3.1]decane obtained in Example 11 (3.50 g) in EtOH (52 ml) underwent hydrogenation at 45 psi and 30° C. for 19 hours in the presence of Pd/C 10% (1.13 g). At the end the mixture was filtered on celite and the catalyst washed with EtOH. The solution was then concentrated. 2.44 g of a light oil corresponding to the compound 3-BOC-3,10-diazabicyclo[4.3.1]decane (12a) are obtained.
