Methyl 1-methyl-8-nitro-1,2-dihydroquinoline-7-carboxylate → Methyl 8-amino-1-methyl-1,2,3,4-tetrahydroquinoline-7-carboxylate

Participants

Reaction Steps

To a solution of methyl 1-methyl-8-nitro-1,2-dihydroquinoline-7-carboxylate (1.25 g, 5.04 mmol) in degassed MeOH (25 mL) at rt was added Pd/C (125 mg). The mixture was stirred under 1 atm H2 for 16 h. The resulting mixture was filtered through celite and concentrated to afford methyl 8-amino-1-methyl-1,2,3,4-tetrahydroquinoline-7-carboxylate in pure form.
