tert-Butyl 4-((4-nitrobenzo[d]oxazol-2-yl)methyl)piperazine-1-carboxylate → tert-Butyl 4-((4-aminobenzo[d]oxazol-2-yl)methyl)piperazine-1-carboxylate

Participants

Reaction Steps

To a solution of tert-butyl 4((4-nitrobenzo[d]oxazol-2-yl)methyl)-piperazine-1-carboxylate (5.97 g, 16.6 mmol, 1.0 equiv) in MeOH (49 mL) was added Pd/C (10% Pd, wet, 2.99 g). The resulting suspension was fixed with a hydrogen balloon and sparged with hydrogen while stirring was maintained. After 1 h, the mixture was filtered through a pad of celite and concentrated in vacuo to provide the title compound as an off-white solid (5.0 g, 91%).
